Abstract: In one embodiment, a differential amplifier (130) is provided. Gates of a first differential pair of transistors (132/134), of a first conductivity type, and a second pair or transistors (146/148), of a second conductivity type are coupled to first and second input terminals of the differential amplifier. A first pair of adjustable current sources (136/138) are configured to adjust respective tail currents of the first differential pair of transistors in response to a first bias current control signal. A second pair of adjustable current sources (152/154) are configured to adjust respective tail currents of the second differential pair of transistors in response to the first bias current control signal. A third pair of adjustable current sources (142/144) are configured to adjust respective currents through the second differential pair of transistors in response to a second bias current control signal.
