Abstract
An amplifier circuit includes a first amplifier stage having a first output node; a second amplifier stage having a second output node; and a compensation block electrically coupled between the first and second output nodes. The compensation block has a compensation capacitor electrically coupled to the first node and electrically connectable to the second node, and has an impedance electrically connectable to the compensation capacitor. The compensation capacitor is electrically coupled via a switch to the impedance such that the compensation capacitor can contribute a zero to shunt branch formed by the compensation capacitor and impedance when the compensation capacitor is disconnected from the second node.
