Amplifiers with a single high gain stage are attractive for their simplicity and excellent power/performance tradeoff, but their typically higher distortion has limited their use in the audio field. Presented here will be a low power single-stage amplifier architecture that enables passive cancellation of distortion (THD < -120 dB, @ 20 kHz). Classical output stage distortion as well as nonlinear capacitive effects will be addressed.
