摘要：
A system and a method are disclosed for providing a constant swing high-gain complementary differential limiting amplifier. High gain for the differential amplifier is created by providing a current to the driving transistors that is a combination of any of (a) constant current, (b) transconductance based current, and (c) temperature compensated based current. A constant differential output swing is created by providing a varying differential current to the output load resistors of the differential amplifier that tracks process and temperature variations within the output load resistors.
