description | A low distortion amplifier. The novel amplifier includes a first transistor Q 1 having first and second output terminals and an input terminal adapted to receive an input signal, and a second transistor Q 2 having first and second output terminals and an input terminal adapted to receive a signal from the first output terminal of Q 1 , wherein the second output terminal of Q 1 is connected to the second output terminal of Q 2 in order to eliminate a nonlinear current component in Q 2 . In an illustrative embodiment, the amplifier also includes a cascode Darlington pair Q 3 , Q 4 for holding the second output terminals of Q 1 and Q 2 at a desired voltage to further reduce distortion and to maintain a wide bandwidth. |
