In this article I have explained about a peak detector circuit, its working principle and how to implement it in clap operated circuits for illuminating an LED in response to clap sounds. What is Peak Detector A peak detector is a circuit which holds maximum amplitude value of a signal. If a signal varies rapidly […]

Automatic Voltage Regulator (AVR) Circuit
An automatic voltage regulator circuit is quite well used where Voltage supply is only 120VAC. Many gadgets can operate good at 220V Ac that is why Voltage regulation is needed. By: Mehran Manzoor For this matter an appropriate voltage Regulator circuit is designed which can operate up to capacity of 1KW and gives Variable voltage […]
High Voltage Battery Charger Circuit
In this post I have explained a simple automatic High Voltage Battery Charger Circuit which can be used for an automatic charging control of any preferred high voltage battery bank such as a 360V battery bank. The idea was requested by “resonance”. Circuit Objectives and Requirements Circuit Diagram The Design The figure above shows a […]
Over Voltage Protection for Automotive Load Dump
In this post I have explained an over voltage cut-off protection circuit in the form of automotive dump load for protecting sensitive and sophisticated modern automotive electronics from transient DC electrical spikes emanating in vehicle electrical. Transient bus voltages are a significant risk factor to integrated circuits. The maximum breakdown voltage that an integrated circuit […]
3 Frequency to Voltage Converter Circuits Explained
As the name suggests frequency to voltage converters are devices that convert a varying frequency input into a correspondingly varying output voltage levels. Here we study three easy yet advanced designs using IC 4151, IC VFC32 and IC LM2907. 1) Using IC 4151 This frequency voltage converter circuit using IC 4151 is characterized by its […]
2 Simple Voltage to Frequency Converter Circuits Explained
A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]
