Würth Elektronik announced the Bluetooth Low Energy 5.1 module Proteus-III and the proprietary version Thyone-I. The modules, measuring only 8 × 12 × 2 mm, with integrated antenna, encryption technology and six configurable IO pins, are based on the Nordic Semiconductor nRF52840 chipset. They can be used for IoT and M2M applications, for example, to build radio-based maintenance interfaces and sensor networks. The WE-ProWare firmware from Würth Elektronik, which has been industrially proven over many years, makes the modules extremely versatile.
Proteus-III exploits the possibilities of the Bluetooth Low Energy 5.1 standard and even goes beyond them. With a payload of up to 964 bytes, the module offers four times the throughput of previous Bluetooth Low Energy modules. It can also establish connections in the newly introduced long range mode to transmit data over long distances. A special feature from Würth Elektronik: Proteus-III offers a good alternative to the SPP (Serial Port Profile) mode for serial data transmission, which is no longer included in the standard but is extremely useful for industrial applications. NFC wake-up and NFC pairing are prepared.
With the proprietary Thyone-I radio module, Würth Elektronik shows what is possible in the 2.4 GHz band: a range of up to 750 m and an end-to-end payload throughput of up to 400 kbps. A simple setup turns modules into repeaters in a mesh network, as required. WE-ProWare is an extremely versatile, easy-to-configure firmware with a lean and powerful radio protocol. If transmission standards are already specified in the application, Thyone-I can easily be converted to ZigBEE, Thread or Wirepas.
Proteus-III and Thyone-I are available from stock without a minimum order quantity. For both modules, Würth Elektronik offers evaluation boards, USB radio sticks with integrated radio module and very user-friendly manuals.

It is in the late 30’s that an American engineer named Hendrick Wade Bode designs a famous representation to study AC circuits in the frequency domain. These graphs are still nowadays very useful in electronics and automatism and are called Bode diagrams.
In this tutorial, we will give every necessary step in order to represent and read Bode diagrams.
First of all, we present every necessary concept that needs to be detailed previously. We will, therefore, give a recap about the notions of the transfer function, gain, and phase.
The following of the article consists of understanding how to read these diagrams, which provides much information about an unknown circuit.
The last section shows how to plot the diagrams of some of the most common electronic circuits. This process is useful to share the information in a compact form of a specific circuit in a manual user for example.
Definitions
The transfer function is the fundamental notion to understand before talking about Bode diagrams. Consider any linear electronic circuit defined by its transfer function T(jω) and represented in Figure 1 by a box, with one input and one output terminal:
fig 1: Quadripole representation of a linear electronic circuit
The transfer function is defined by Vout=T(jω)×Vin with Vin=|Vin|ejωt. Sometimes, we can note p or s=jω which is known as the Laplace variable.
From this transfer function, two important parameters can be computed. The first one is the gain/amplitude (G), which is found by taking the norm of this complex function: G=|T(jω)|. In order to plot Bode diagrams, it is the gain in decibels (GdB) that is considered: GdB=20log(G).
A gain GdB=0 indicates that the norms of the input and output are equal |Vin|=|Vout|, this is called a unitary gain. When GdB tends to infinite negative values, no output is observed despite the presence of an input.
The second important parameter is the phase difference (ΔΦ) between the input and output. This phase difference is given by the argument of the transfer function: arg(T(jω))=ΔΦ. This equality comes from the fact that if we consider a ratio of complex numbers z1/z2, the argument is given by the differences of the arguments of the numerator and denominator, which proves the previous formula: arg(z1/z2)=arg(z1)-arg(z2).
Presentation of Bode diagrams
The Bode diagram of an electronic circuit consists of two graphs that plot respectively the gain GdB and the phase difference as a function of the frequency in logarithmic scale. Both of these graphs can have two representations that are shown in Figure 2: the real or asymptotic representation.
The real curve is associated with the analytical expression of the norm and the argument of the transfer function. The asymptotic representation is a straight-line approximation also known as Bode pole. In this section, we study the Bode diagrams of a simple series RC low-pass filter which circuit is represented in the third section.
fig 2: Real and asymptotic representations of a low-pass filter
Figure 2 gives a lot of information, but in order to make it more clear and easy to read, we consider the real representations of the gain and phase plots separately in Figure 3 and Figure 4 as following.
fig 3: Focus on the gain plot
The gain plot is divided into two regions labeled pass band and stop band which common border is defined by the cutoff frequency fc and in this example is equal to 10 kHz. The pass band is the region where the gain is constant and equal to 0 dB (in the Bode pole approximation), the stop band is the region where the gain is strictly smaller than -3 dB and drastically decreases, this value and rate are commented more in detail in the following.
This specific frequency is characterized by GdB(fc)=-3 dB, but why is this value so relevant? Even if each circuit has different expressions for the transfer function and the cutoff frequency, the amplitude is always divided by √2 at fc: |T(fc)|=|Tmax|/√2. When converting this ratio in dB, it comes that 20log(1/√2)=-3.
The importance of this value comes from the fact that the power is proportional to the square of the amplitude, hence when the amplitude is divided by √2, the power is divided by 2.
The cutoff frequency defines the frequency at which a loss of half of the power is observed.
One last fact can be commented in Figure 3, it is indeed highlighted that at 100 kHz the gain is -23 dB. Since at 10 kHz the gain is -3 dB, we observe a loss of -20 dB per decade, also written -20 dB/dec. We will see later in the third section that this value is typical from a first-order filter.
We can also extract some information from the phase plot shown in Figure 4 below:
fig 4: Focus on the phase plot
Here the same cutoff frequency marks the border between the resistive and reactive behavior. At fc, the phase-difference is indeed equal to -45°. Before fc, the circuit behaves more like a resistor, in DC and low-frequency regime, it is purely resistive. After fc, the capacitance effect increases and at high frequencies, the circuit becomes purely reactive.
Common Bode diagrams
First-order filters
The previous section presents the Bode diagram of a series RClow-pass filter which circuit is represented in Figure 5:
fig 5: Series RC low-pass filter
We have seen that this filter is characterized by its cutoff frequency fc=1/(2πRC), and it’s gain roll-off of -20 dB/dec. Let’s now consider another type of filter that can be realized with a parallel RC circuit shown in Figure 6:
fig 6: Parallel RC circuit
It can be shown that the transfer function of this circuit is given by Equation 1, with p=jω.
eq 1: Transfer function of the parallel RC circuit
When plotting the Bode diagrams associated with this transfer function, it becomes clear that the parallel RC circuit is a high-pass filter:
fig 7: Bode diagrams of the parallel RC high-pass filter
For this example, we chose the same values of R and C than for the low-pass filter so that the cutoff frequency remains unchanged and equals 10 kHz.
Concerning the gain plot, we can say that it is the symmetrical plot of the low-pass filter with the vertical line given by the cutoff frequency value as the symmetrical axis. The pass and stop bands are inversed and a positive slope is now observed, which rate from the DC regime to the cutoff frequency is +20 dB/dec.
In fact, every first-order filter is characterized by an absolute value of 20 dB/dec for the roll-off or increase of the gain.
From the association of Bode diagrams, we can understand how band-pass and band-stop filters can be made. Consider indeed a low-pass and high-pass filters which cutoff frequencies are respectively fcl and fch. A band-stop filter behavior is observed if fcl<fch:
fig 8: Gain plot of the low-pass and high-pass association
In this example, fcl=10 kHz and fch=20 kHz, the band-stop-width is therefore given by Δf=fch-fcl=10 kHz. The resonance frequency f0 is given by the geometrical mean of the cutoff frequencies: f0=√(fcl+fch)≈14 kHz. The gain plot of the band-stop filter is given by the logarithmic addition of these two curves:
A band-stop filter can be realized in practice by associating an RC high-pass filter in parallel with an RC low-pass filter and choosing appropriate values for the resistor and capacitor in order to observe the desired behavior.
The dual-circuit of the band-stop filter can be made with the series association of the same RC filters. In this case, the cutoff frequencies must respect the inequality fch<fcl:
fig 9: Band-pass filter gain plot
The formulas for the bandwidth and resonance frequency still apply for the band-pass filter.
Second-order filters
Second-order filters are characterized by the presence of at least one term p2 in the expression of their transfer function. This term comes from the fact that two reactive components are present in the circuit.
We have already presented in the Series RLC circuit and Parallel RLC circuit tutorials two circuits that respectively make second-order low-pass and high-pass filters. Their associated transfer function and Bode gain plots are also shown in these articles.
Second-order filters have the advantage of having a roll-off (for the low-pass filter) or an increase rate (for the high-pass filter) of 40 dB/dec in absolute value, therefore, rejecting faster the undesired frequencies.
Such as for first-order filters, second-order band-stop and band-pass filters can be realized with the parallel or series associations of the elementary RLC low-pass and high-pass filters.
Conclusion
Bode diagrams are a visual and efficient tool to represent the AC behavior of an electronic filter. They are associated with the transfer function of the circuit from which the gain and phase difference can be computed.
Bode diagrams can be plotted through some experimental methods in order to study and characterize an unknown circuit. The measure of the cutoff frequency, bandwidth (for band filters) and slope help us to determine the order, the components and the architecture of a circuit.
On the other hand, the knowledge of Bode diagrams of the elementary filters is essential to anticipate the behavior of a circuit and design customized filters.

AAEON, an industry leader in hardware solutions, announces their latest network appliance, the FWS-2275. Built rugged and designed to power a range of network applications, the FWS-2275 brings vital functions and security to industrial networks.
As more and more industries move towards connecting sites and devices through edge computing and Industrial IoT (IIoT) environments, network security is becoming more important than ever. Recent activity by hackers have shown a shift in focus towards attacking connected infrastructure. Industrial networks are often less developed and less secure than central servers, leaving a glaring weak spot as many companies begin to adopt Industry 4.0 solutions.
AAEON has introduced the FWS-2275 as a hardware solution to help solve the issues of network security in industrial environments. The FWS-2275 is powered by the Intel® Celeron® N3350 processor (formerly Apollo Lake) with built-in Intel® AES-NI, providing data encryption that is secure with faster processing than standard AES. The FWS-2275 is designed to power network solutions such as UTM, firewall, and SD-WAN. The FWS-2275 also includes on-board Wi-Fi, USB mini Console, and SIM card slot. The FWS-2275 can also be deployed as an Industrial IoT (IIoT) gateway or edge computing device.

Torex Semiconductor Ltd. has launched the XCL230/XCL231 as a new series of low supply current, 36V, 600mA step-down dc-dc converters with integrated inductors. Integrating the coil makes for easier circuit board layout and minimizes malfunction and noise from the component and wiring layout.
The input voltage range is 3.0- to 36-V, the switching frequency is 1.2MHz, and a synchronous rectification circuit is used to achieve a stable power supply at high efficiency. The DFN3030-10B (3.0×3.0, h=1.6mm) package is used for a small package size.
The XCL230 Series fixes the operation frequency using pwm control to suppress output ripple voltage. The XCL231 Series automatically switches between pwm and pfm control to reduce loss by lowering the operation frequency during low loads to achieve high efficiency across the entire range from low to high loads. A 0.75V standard voltage supply is built in, and the output voltage can be set to 1.0V to 5.0V using an external resistance.
The “cool post type” package used in XCL230/XCL231 series allows the upper coil to be connect to the PCB with low resistance in both electricity and heat by penetrating the Cu post inside. Low resistance and high heat dissipation can be realized.
The soft start time is internally set to 2.0ms, and a time that is longer than the internal soft-start can be freely set depending on the resistance and capacity connected to the EN/SS pin. An overcurrent protection function and thermal shutdown function are built in as protective functions to ensure safe use in the event of a short circuit.
