Every amplifier takes in some kind of input signal (a certain current and voltage, which, together multiply to give a certain power level) and produces a bigger output signal (which may have a different current, voltage, or power). One very basic classification we can make is between voltage and power amplifiers.
EETimes - How Class D audio amplifiers work
https://www.eetimes.com/how-class-d-audio-amplifiers-work/
It is common in Class D amplifiers to use feedback to compensate for the bus voltage variations. Energy Flow – In linear amplifiers the energy flow is always from supply to the load, and in Full bridge Class D amplifiers this is also true. A half-bridge Class D amplifier however is different, as the energy flow can be bi-directional, which leads to the “Bus pumping” …

2.3 Transistor Common Base Amplifier. The common base amplifier is something that you rarely see these days. It was also used in valve circuits and was sometimes called a 'grounded grid' amplifier. Input impedance is very low, and the circuit shown has an input impedance of around 50 ohms. It has high gain, and can be used at radio frequencies because there is almost no …
