Welcome to IOU Digital Library

This work presents a straightforward MOSFET-based audio amplifier design. The amplifier operates in Class AB, delivering approximately 100 W RMS under 8 ohms or 160 W RMS under 4 ohms. It boasts excellent linearity with a distortion rate of about 0.1%. The frequency response is from 4 Hz to 96 kHz, limited by specific components. The output MOSFETs are biased with a quiescent current adjustable between 50 to 100 mA using a potentiometer.
