Simple Boost Converter Circuit Diagrams using Transistors

Last Updated on January 27, 2025 by Swagatam Leave a Comment

boost converter working model

In this post I have explained a few very simple boost converter circuits using only BJTs, or transistors. Let’s learn more. What is a Boost Converter A DC boost converter circuit is designed for stepping-up or boosting a small input voltage levels to a desired higher output voltage level, hence the name “boost” converter. Since […]

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 […]
