Class A Mosfet Headphone Amplifier

11/24/2008 Category: Amplifier, Analog, Audio, Project

This is a simple and low cost desktop headphone amplifier for the office. The amplifier concept is simple and follows a typical single-ended class A circuit utilizing an active constant current source (CCS) in place of a passive resistor. A CCS doubles the efficiency of the circuit over that where a passive load resistor is used, bringing it to a maximum of 25%.
