Op Amps: Single Supply Biasing



Published
In this video we examine how to run a basic op amp circuit from a single DC supply. Extra components are added to create a midpoint bias which prevents inadvertent clipping. We also introduce a method to decouple the bias from the input signal, which reduces potential problems from non-ideal power supplies.
