Class A Amplifiers
Class A Amplifiers are a type of electronic amplifier known for their high linearity and low distortion. They operate by conducting over the entire input signal cycle, which means they are always "on." This results in a smooth and accurate amplification of audio signals, making them popular in high-fidelity audio applications.
However, Class A Amplifiers are not very efficient, as they generate a lot of heat and consume more power than other amplifier classes. Typically, they have an efficiency of around 20-30%, which can lead to increased energy costs and the need for effective cooling solutions in their design.
