Simple Class A Amplifier Circuit

Last updated on 5 June 2025 by Admin-Lavi Leave a Comment

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 we can construct one by using Q1 and Q2 transistors […]
