About this document
Large-Signal Amplifiers Overview by Kumbirayi Nyachionjeka is a document available to read on EtoBox.
This document discusses different classes of amplifiers including class A, B, AB, C, and D. Class A amplifiers operate over the entire cycle but have low efficiency around 25%. Class B amplifiers operate for half the cycle and have higher efficiency but also distortion. Class AB reduces distortion by adding some forward bias. Class C uses tank circuits to restore signals and has highest theoretical efficiency of 100% but a small conduction angle. Class D or switch-mode amplifiers use pulse width modulation
