Introduction This circuit presented in this post, an APD bias circuit, generates a low-noise bias voltage for avalanche photodiodes (APDs). The circuit employs a low-noise fixed-frequency PWM DC-DC

In this article we discuss a UPS circuit powered from mains supply. The backup power is provided by NimH batteries. Figure 1 : UPS schematic   The power

Introduction Radiation detection systems often consist of a detector, a charge sensitive pre-amplifier, a pulse shaping amplifier and a multi-channel analyser. The detector converts interaction of photon energy from an

The post briefly shows a circuit that could be used to transmit data optically (through the air) to a receiver. In this case, we made a circuit to

This tutorial post is on how to build a simple thermistor circuit. There is a variety of temperature sensors on the market all of which meet specific application needs.

This post describes the use of an ultrasonic sensor to measure distance of a target. The goal of this post is to help you understand how this sensor works
