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 […]
