Differential amplifier with gain linearization through transconductance compensation |
摘要 |
Disclosed is a differential amplifier including an emitter follower pair, a first differential pair, and a main differential amplifier. The emitter follower pair is operative to receive an input differential voltage signal for shifting the input differential voltage signal to develop a shifted differential voltage signal. The first differential pair is configured to feed a first differential current inversely to the emitter follower pair so that a transconductance of the emitter follower pair changes inversely to compensate for a change in a transconductance of the first differential pair. The main differential amplifier is coupled to receive the shifted differential voltage signal and is configured to amplify the shifted differential voltage signal to generate an output voltage signal.
