Abstract
A differential amplifier includes a first electrical path formed between a first transistor and a first load impedance; a second electrical path formed between a second transistor and a second load impedance; a tail-current transistor coupled to the first and second transistors; an input end of a feedback amplifier coupled directly to the first and second electrical paths for receiving a differential voltage output signal; and an output end of the feedback amplifier coupled directly to the tail-current transistor for adjusting the current provided through each of the first and second electrical paths. The feedback amplifier includes a non-inverting input node and an inverting input node, each node coupled directly to one or the other of the first and second electrical paths.
