Abstract
Utilizing the high gain and high input impedance of short channel power MOSFETs, a simple circuit has been devised to provide sufficient drive for amplifiers up to 200 watts output. The circuit described features automatic control of the quiescent bias level and offers performance which meets criteria for high quality audio reproduction.
