Figure 1: A Class A audio amp is typically associated with high linearity but low efficiency. Class B Amplifiers Class B amps use a push-pull amplifier topology. The output of a Class B amp incorporates a positive and negative transistor. To replicate the input, each transistor only conducts during half (180°) of the signal waveform (Figure 2). This allows the amp to idle …
Amplifier Topologies (Classes)
https://blog.down4soundshop.com/amplifier-topologies-classes/
These are the two topologies on which the class A/B amplifiers are based. Class A Class A amplifiers utilize all of the audio signal input, all of the time. This means that the amplifier is duplicating the signal from the head unit, or audio source, with little to no clipping or distortion.

Tommy--OBrien. The class of an audio power amplifier describes the way it's output devices are used. Back in the mid-1900s, amplifier classes were defined as Class-A, Class-B, Class-D and several others (Class-C, -G, -S, etc). Class-A, Class-AB, and Class-D are the primary topologies found in modern amplifiers, with the other classes largely variations of the three …

The first amplifier topology we will investigate is called Class A. This is one of the simplest systems, as it really only requires one output device per channel. Oh yeah, output devices. That's what topology is all about. Every amplifier has a set of voltage rails.

At low frequencies, the standard amplifier topology shows a mixed distortion residual, while the new amplifier architecture is still limited by noise and oscillator/analyzer contributions. Above 1 kHz, both model amplifiers show increasing distortion levels, however the magnitude observed for the novel transimpedance stage remains about dB below that of the …
