FesZ Electronics | The Class A amplifier - basics and simulation (1/2) @FesZElectronics | Uploaded March 2022 | Updated October 2024, 7 hours ago.
#152 In this video I am looking at some of the main aspects regarding the Class A operation of amplifiers. I will check out how the gain of a transistor is not really fixed so to see why you need some way to stabilize the gain and then look at the various ways in which loads can be connected to the amplifier, and how this has an impact on efficiency.
