Introduction. In theory, capacitor-coupled output stages are completely straightforward, and there''s no uncertainty about how they work. We all know that a capacitor passes AC and blocks DC, but with a single-supply power amplifier (or any other Class-AB single-supply circuit for that matter), current is only drawn from the power supply with positive half-cycles.

Bypass Capacitor and Coupling Capacitor: Stabilizing Voltage

Figure 1. ADP2441 switching regulator with the bypass capacitor C BYP at the input..
