摘要： An amplifier may include first and second terminals to receive first and second input signals and a differential amplifier providing differential amplification of the first and second input signals. The differential amplifier may include a first differential amplifier stage to receive the first input signal and a second differential amplifier stage to receive the second input signal. The amplifier may further include a first bias circuit to bias the first differential amplifier stage, where the first bias circuit is connected to the second input terminal to provide anti-phase bias control of the first differential amplifier stage. The amplifier may further include a second bias circuit to bias the second differential amplifier stage, where the second bias circuit is connected to the first input terminal to provide anti-phase bias control of the second differential amplifier stage.
