Abstract
The present invention teaches a variety of output stages for amplifying high speed signals while keeping distortion low and using a low supply voltage. The invention includes the use of dual complementary signal paths that include a complementary push-pull output stage. Bias circuits are used to keep the paths symmetrical and positive feedback is used to oppose output loading effects.
