If phase noise is a critical project design consideration then it is important to realize that vibration causes a degradation in both spectral output and phase noise. Even moderate levels of vibration can significantly introduce an unwanted signal variation. The acceleration-sensitivity (“g-sensitivity”) of components is often a limiting factor in these applications, and quartz crystals often prove to be a critical limiting component in a design.

In the introduction tutorial Operational Amplifier Basics, we have briefly seen that from the same op-amp, many configurations leading to different functions can be adopted, depending on how the feedback loop is designed.
In this new tutorial, we propose to detail the most common configurations along with their function.
We chose to group the configurations in three distinct major groups which will constitute the sections of this tutorial. The first section will, therefore, focus on the buffer designs,
The second section presents the amplifier configurations whose goal is to amplify a signal. Finally, the third section presents the operational op-amps which transform one or more signals to perform elementary mathematical operations.
Buffer configurations
A buffer amplifier is a block that is placed between two circuits which impedances are not matching: a high (resp. low) output impedance connected to a low (resp. high) input impedance. The goal of the buffer is to insulate the stages from each other and perform an impedance adaptation.
Since our tutorial concerns op-amps, we will only talk about voltage buffers but there are also current buffers.
Voltage follower
The voltage follower is a buffer that does not amplify nor inverts the signal. Consequently, its gain is equal to +1. The design of the voltage follower is very simple and simply consist of a short-circuit feedback to the inverting input (-) of the op-amp:
fig 1: Voltage follower circuit
In order to really understand the purpose of this circuit, consider a Thevenin sourceVThwith an internal series resistance RTh that supplies an output load RL such as shown in Figure2:
fig 2: Thevenin source driving a load
Due to the voltage division phenomenon, the source (VTh, RTh) will only be able able to provide a voltage VThRL/(RL+RTh) to the load. Let’s now place a voltage follower circuit between the source and the load:
fig 3: Voltage follower in a Thevenin circuit
If we label Zin the input impedance of the op-amp, the voltage provided to the amplifier is Vin=VThZin/(Zin+RTh). However, since the input op-amp impedance is very high (Zin>>RTh), or even infinite if we consider the amplifier to be ideal, the input voltage in the op-amp can actually be simplified to Vin=VTh.
Since the voltage follower has a gain of +1, the output voltage is Vout=VTh. The voltage provided to the load can be written VThRL/(RL+Zout), however, the output impedance (Zout) of an op-amp is very low (Zout<<RL) or even equal to zero if we consider the op-amp to be ideal. As a consequence, the voltage provided to the load can be simplified to VTh.
In that example, we can see that the voltage VTh is entirely provided to the output load without any division phenomena thanks to the voltage follower. The circuit shown in Figure 3 actually acts as an ideal voltage source with zero Thevenin internal resistance.
Inverting buffer
If we consider the circuit in Figure 1, add resistors in the feedback loop and inverting input, and connect the non-inverting input to the ground, we obtain a circuit known as inverting buffer:
fig 4: Inverting buffer circuit
Assuming that the value of the resistors is strictly identical under the working condition of the op-amp, the gain of this circuit is -1. The signal is therefore not amplified but inverted: Vout=-Vin.
Amplifier configurations
In this section, we present some configurations for which the op-amp act as an amplification device, meaning that Vout>Vin.
Non-inverting amplifier
We consider a similar circuit to the one presented in Figure 4, the resistors are, however, not necessarily of similar value and the input signal is provided to the non-inverting input (+):
fig 5: Non-inverting amplifier circuit
The gain Vout/Vin of the non-inverting amplifier is always strictly higher than +1 and given by Equation 1:
eq 1: Non-inverting amplifier gain
Inverting amplifier
The inverting amplifier is designed by grounding the non-inverting input and applying the signal to the inverting input in the circuit presented in Figure 5.
fig 6: Inverting amplifier circuit
The gain is given here by the ratio -R1/R2, the negative sign assures that the signal is inverted.
Bridge amplifier
An inverting and non-inverting amplifier can be connected together to form a bridge amplifier. In this circuit, the input is common to both amplifiers while the output is taken on a load RL that is connected between the outputs of the amplifiers.
fig 7: Bridge amplifier circuit
According to the previous subsections, the output of the first amplifier will be A1Vin with A1=-R1/R2. The output of the non-inverting amplifier is A2Vin with A2=1+(R3/R4).
Finally, with the direction convention chosen for Vout, the output of the bridge amplifier is given by (A1-A2)Vin. We can note that if the resistors are appropriately chosen, the magnitudes of the gain can be equalized (|A1|=|A2|), which allows the bridge amplifier to increase by a factor 2 the maximal amplification that a single amplifier could perform.
The advantage of the bridge amplifier is to be able to supply more power to an output load, by a factor 4. Moreover, a single-supply is able to drive both amplifiers that constitute the bridge amplifier, thus simplifying the design and cost of the circuit.
Operational configurations
Some op-amps configurations can perform elementary mathematical operations. In the following, we present the adder/subtractor and the derivator/integrator circuits.
Adder/subtractor
The adder configuration takes several voltages on its inverting input connected via resistors.
fig 8: Adder circuit with N inputs
In the general case, the voltage Vout satisfies Equation 2:
eq 2: Adder configuration formula
It is interesting to equalize all the resistances RA=R1=…=RN, which leads to a simplified formula where we can clearly see that the configuration presented in Figure 8 effectively adds the voltages:
eq 3: Simplified adder configuration formula
Note that the presence of the minus sign means that the voltage sum is inverted. In order to add the voltages without an inversion, we can simply place an inverting buffer after this stage.
To realize a subtractor configuration, both the inverting and non-inverting output are used such as shown in Figure 9:
fig 9: Subtractor circuit
The configurations become again interesting when the resistor values are appropriately chosen so that R–=R1 and R+=R2. In that case, the subtractor function can be performed:
eq 4: Subtractor configuration formula when R–=R1 and R+=R2
Derivator/Integrator
We start with the derivator which input is connected via a capacitor to the inverting branch, the feedback loop is connected with a resistor:
fig 10: Derivator circuit
The output is proportional to the variations of the input signal given by the derivative function:
eq 5: Derivator configuration formula
Derivators are useful to control the variations of certain physical parameters previously transformed in an electrical signal such as the temperature, pressure…
By inverting the position of the capacitor and resistor in Figure 10, we obtain the circuit of an integrator:
fig 11: Integrator circuit
For this circuit, the output is proportional to the integral of the input:
eq 6: Integrator configuration formula
Conclusion
We have presented in this tutorial some of the most important building blocks that can be realized with operational amplifiers. We chose to distinct these configurations in three groups depending on their function.
In the first section, we focused on the buffer configurations which do not amplify or modify the signal. The buffers can either be non-inverting (Vout=Vin) or inverting (Vout=-Vin) depending on which input the signal is applied. Thanks to their high input and low output impedances, buffers are mainly used to connect unmatching circuits together.
Amplifier configurations are presented in the second section with again, a distinction being made between inverting and non-inverting amplifiers. In both cases, it is the values of the resistors connected to the inverting branch that will dictate how much the output signal will be amplified. To conclude this section, we have presented the bridge amplifier which consists of interconnecting an inverting and non-inverting amplifier in order to increase the power that can be supplied to the output load.
Finally, operational configurations that can perform elementary mathematical operations are presented in the last section. An adder amplifier can be realized with an inverting op-amp with multiples inputs, a subtractor is realized with inputs on both inverting and non-inverting inputs. In both cases, it is interesting to equalize the resistors present in the circuit in order to realize additions and subtractions with any prefactor. Moreover, integrator and derivator designs are presented, they both have a capacitor in their design and are used either to integrate or derivate the input signal, these functions are widely used in automation.

“Especially on the cloud side, our aim is to take care of the “underlying” complexity by performing code generation and automation at every possible step of the process. Combining the ease of build with the ability for users to leverage their mobile device as a control interface through specialized apps for Android and iPhone, we’re excited to make simple and secure IoT possible for everyone.”
The partnership brings 5G-ready NB-IoT over satellite for the first time and delivers massive cost and interoperability advantages for the IoT industry
Skylo, maker of the world’s most affordable and ubiquitous network that connects any machine or sensor, today announced a partnership with Sony Semiconductor Israel (Sony, formerly known as Altair Semiconductor). With the partnership, Skylo and Sony are the first to develop and deploy cellular IoT chipsets (branded “Altair”) that can connect via geostationary satellites and that leverage the standardized, 5G-ready, NB-IoT protocol. The partnership also makes significant contributions to 3GPP future specifications, which will help standardize and accelerate the adoption of NB-IoT over satellite. In addition, this innovative new use of Sony’s Altair cellular IoT chipsets dramatically reduces the cost for IoT applications to connect via traditional satellite networks; until the launch of this solution, satellite connectivity was cost-prohibitive and required custom-built protocols.
Skylo, which was founded in late 2017 by foremost researchers including Dr. Andrew Kalman, is building an efficient, global NB-IoT network over satellite for millions of presently unconnected devices, machines, and sensors. Sony Semiconductor Israel is a leading provider of cellular IoT chipsets. Through this partnership, both parties have extended existing cellular IoT chipsets to communicate directly over Skylo’s hosted satellite network.
“For industries with assets deployed all over the globe — including marine vessels, vehicles, and industrial equipment — having access to a ubiquitous fabric of carrier-grade, affordable IoT connectivity that is enabled by Sony’s Altair cellular IoT chipsets is a game-changer,” said Dr. Andrew Nuttall, Skylo’s co-founder, and CTO. “This partnership ensures our ability to quickly scale the manufacturing and deployment of connector Skylo Hubs to our customers worldwide.”
“We are glad to collaborate with Sony Semiconductor Israel on this important technological breakthrough, which provides an entirely new connectivity method for IoT for customers around the world and contributes greatly to the development of future 3GPP standards,” said Moshe Noah, Vice President of Engineering at Skylo.
“We are excited to work with Skylo and launch an entirely new IoT category for industrial machines,” said Dima Feldman, Vice President of Product Management and Marketing at Sony Semiconductor Israel. “We’re impressed by the innovative way that Skylo has extended our chip functionality over satellites to expand the connectivity reach to the most remote locations. We look forward to helping Skylo bring billions of sensors online for the first time.”
“In addition, the Altair field-proven, ultra-low-power, and ultra-small chipset solutions are ideal for the type of data exchange for industrial use cases,” added Feldman.
This new geostationary satellite connectivity is a technological breakthrough for Skylo. Any customer who is building IoT into their remote businesses can use familiar technologies like Bluetooth and WiFi in order to connect existing sensors to Skylo Hub. Those IoT sensors are already programmed for these communications protocols. Adding Skylo’s satellite connectivity is a seamless extension for customers that, in addition to terrestrial networks, can now use satellite connectivity, virtually in any place on the planet. In addition, because Sony’s Altair cellular IoT chipsets are mass-produced for terrestrial cellular networks, Skylo can affordably manufacture the Skylo Hub and pass along that savings to its customers.
Skylo is launching commercially this year over South Asia and can be accessed using the Skylo Hub, a portable satellite NB-IoT antenna terminal. The Skylo Hub costs less than $100 USD and integrates seamlessly with existing machines & sensors. The Skylo Network is hosted on existing geostationary satellites and enables immediate connectivity for customers without the need to add new infrastructure in space. Skylo is venture-backed by leading investors in telecom and space, including SoftBank Group, Boeing HorizonX, Innovation Endeavors, and DCM Ventures.
Optically isolator Arduino Shield has been designed to provide optically isolated I2C communication between Arduino and any other device or sensors that works with I2C protocols. I have used the ISO1540 Low-Power Bidirectional I2C Isolator IC from Texas Instruments to build this project, and the device is compatible with I2C interfaces. These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2) barrier. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging the Arduino board. The ISO1540 has two isolated bidirectional channels for clock and data lines. The project is suitable for multi-master applications. For applications where clock stretching by the slave is possible. LED D1 is the power indicator for side two. This board requires two separate supplies, side one powered from Arduino UNO 5V, side 2 require separate 3.3V to 5V.
