Provided herein are amplifiers including negative capacitance circuits for reducing distortion resulting from a gate-source (or base-emitter) capacitance of output stages of such amplifiers. Such a negative capacitance circuit is connected in parallel with the gate-source (or base-emitter) capacitance of the output stage to shunt the gate-source (or base-emitter) capacitance and thereby reduce distortion. Also provided herein are methods for use with amplifiers including an output stage, including connecting a negative capacitance circuit in parallel with a base-emitter capacitance of the output stage.
