Abstract
A low distortion amplifier. The novel amplifier includes a first transistor Qhaving first and second output terminals and an input terminal adapted to receive an input signal, and a second transistor Qhaving first and second output terminals and an input terminal adapted to receive a signal from the first output terminal of Q, wherein the second output terminal of Qis connected to the second output terminal of Qin order to eliminate a nonlinear current component in Q. In an illustrative embodiment, the amplifier also includes a cascode Darlington pair Q, Qfor holding the second output terminals of Qand Qat a desired voltage to further reduce distortion and to maintain a wide bandwidth.
