Abstract
A Darlington complementary circuit including first and second signal channel Darlington pairs each of which pair has an input and output transistor, wherein a diode is coupled in series with the base-emitter path of the output transistor of each pair to assure simultaneous turn-off of the transistors of each pair, and thereby prevent distortion of an output signal as one pair ceases operation and the other pair begins operation.
