ABSTRACT:
An amplifier includes an amplification path and multiple offset-compensation feedback paths. The amplification path has multiple amplifier stages, and the feedback paths are coupled to the amplification path. By including multiple feedback paths, such an amplifier can maintain its output DC-offset voltage at a desired level over a full range of amplitudes, i.e., power, of the input signal.
