The class A amplifier circuit type discussed in this post is suitable for tiny speakers or headphones. Amplifiers enhance the volume of sounds. Class A amplifiers use roughly 20 milliamperes of energy making them suitable for devices with lesser power requirements. This article explains how to construct one by using Q1 and Q2 transistors that […]

Let us find out into the working and construction details of this circuit: Circuit Working: Parts List: Category Component Quantity Resistors 100k 1/4W CFR 1 1k 1/4W CFR […]
Simple MIC Preamplifier Circuit using an Op-Amp
This article explain how to build a microphone amplifier circuit using a chip called the IC LM358. Regular microphones have very weak signals and this amplifier makes them much stronger. This circuit is better than simpler designs because it uses a special chip called an operational amplifier op amp. This makes the signal stronger without […]
Simple IC 555 Amplifier Circuit
The IC 555 chip is quite helpful in a lot of electronic circuits. This project differs slightly from the usual usage in timing circuits. We will build a microphone amplifier in this project using the IC 555. Initially, your voice is captured by a microphone. It then gets a modest boost via a transistor which […]
