10 Easy Op-amp Oscillator Circuit Diagrams Explained

Last Updated on January 17, 2025 by Swagatam 5 Comments

formula for calculating C1 and L1

In an op amp oscillator circuit, an op amp is configured with a resistor-capacitor feedback loop or a inductor-capacitor feedback loop, which triggers the op amp to go into an oscillating mode, generating a switching ON/OFF pulses from its output pin. The high-gain and wide passband of operational amplifier (op amp) ICs makes it possible […]

7 Easy Sawtooth Waveform Generator Circuits using UJT, IC 555, and Transistors

Last Updated on January 12, 2025 by Swagatam 2 Comments

swatooth generator circuit compressed

In this post I have explained how to build 7 types of easy sawtooth generator circuits, using BJTs, UJTs, and IC 555. In a sawtooth waveform the voltage increases slowly in a slanting manner or diagonally, then as soon as it reaches the peak, the waveform voltage suddenly drops to zero. Once it drops to […]
