Abstract

See full text

An amplifier circuit with improved accuracy is provided that comprises a cascade of amplifier stages, a control line for controlling the amplifier stages, a feedback circuit having an input port for receiving a reference signal, and a feedback loop connecting the feedback circuit to the control line. Via the feedback circuit and the feedback loop, the large signal behavior of the amplifier stage is accurately fixed. As a result, the small signal gain of the amplifier stages has an improved accuracy as well.
