Let's explore the basic DNA of an audio amplifier. This internal structure not only describes the majority of audio amps today, but also the innards of most op amps today. The design of these amplifiers share 3 common building blocks. Designers optimize the gain, linearity or power in various stages depending on the requirements - from a cheap headphone amplifier to a high performance 100W sound system. And this gives rise to the vast number of different types of audio amplifiers and op amps running around the universe today. We'll build an audio amplifier and follow the signal through the structure. Finally, you'll get a chance to vary components to see their effect on performance.
By the way, there's enough literature on the design and analysis of audio amps to choke a horse. We'll try to hit the essential points. The basic amplifier above is a great place to start. But wait, there's more! In other topics, we'll explore each stage and enhance it. With the help of some hands-on SPICE simulations, you'll understand every component, its role, and how to make a reasonable design choice about i
