In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]

Audio Clipper and Compressor Circuits Explained
In this article I have explained using circuit diagrams how a clipper and a compressor circuits work to processes an input audio signal as per the required output signal. What is an Audio Clipper An audio clipper circuit is basically used to alter or restrict the amplitude (volume) of an audio signal. There are mostly […]
Explained: MAX4466 Electret Microphone Amplifier Module with Adjustable Gain
In this post we will be talking about this MAX4466 microphone amplifier module, right? So this is a tiny little circuit that can amplify weak sound signals from an electret condenser microphone (ECM). That means it is going to take a very small electrical signal from the microphone and then boost it up so we […]
OCL Amplifier Explained
In the field of audio amplifiers OCL stands for Output Capacitor-Less Amplifier design. How it Works In this OCL type of amplifier topology or configuration, the power output stage is directly coupled to its preceding driver stage without coupling capacitors. The following figure shows a typical OCL amplifier output stage, as can be seen, the […]
2 Mosquito Swatter Bat Circuit Diagrams Explained
Mosquitoes are a big menace to humankind and these are present in every corner of the world. A cool way of avenging yourself could by eliminating these “devils” through electrocution. A mosquito swatter bat is designed just for this. I have explained how to build its electronic circuitry. The idea was requested by Mr. kathiravan d. […]
L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
