Priority Encoder The Priority Encoder is a combinational logic circuit that produces an equivalent binary code at its output pins, unique to each combination state of its inputs. As discussed in previous articles, an encoder produces a unique binary code that is related to a specific...

This isolated single-supply bidirectional current sensing project can accurately measure load currents from –2A to 2A. The linear range of the input is from –250mV to 250mV with a differential output range of –2.05V to 2.05V. The gain of the circuit is fixed at 8.2V/V.  The...

This project can be used in bidirectional high-voltage measurements. The output is fully isolated from the input side and can be used for applications such as high-voltage DC-DC converters, High-Voltage EV chargers, SMPS, 3 Phase motor drivers, inverters, etc. The board is built using...

Optically Coupled Power MOSFET Relay with Galvanically Isolated Current Monitor Output This project employs CPC1718J 100V Single-Pole, Normally Open DC-Only Power Relay and ACS71240 Galvanically Isolated Current Sensor IC with Common-Mode Field Rejection and Overcurrent Detection....

British on-device deep learning hardware platform manufacturer InferSens has launched a battery-powered ultra-low-power edge deep learning sensor for commercial and industrial applications. The hardware platform uses Syntiant’s NDP120 neural decision processor to enable highly...

Introduction In the first part of the “Fourier Analysis” article, we have focused on the properties and usages of the Fourier series. We have seen the power of Fourier series as a tool for both decomposing and constructing general periodic functions in terms of “pure" sines and...

The step-down DC-DC Converter project presented here provides 3.3V @ 1A output from an input range of 8V to 36V DC. The adjustable current limit is an important feature of the project, which prevents the device from accidental output short circuits avoiding excessive load damage. The...

Introduction This subject was first assumed by Isaac Newton about 400 years ago. Newton showed that white light is composed of other colors. He called the color components of white light as “spectre”, from which we get the word spectrum. Figure 1 shows how a light beam is dispersed...
