  • Patent number: 7880544
    Abstract: A differential amplifier includes a first pair of differential amplifiers and a second pair of differential amplifiers. These first and second pairs of differential amplifiers are connected between first power rails and are arranged to receive a differential input signal. Third and fourth pairs of differential amplifiers are connected between second rails and also connected to the differential input signal. A current summer sums a first output current of the first pair of differential amplifiers, a second output current of the second pair of differential amplifiers, a third output current of the third pair of differential amplifiers and a fourth output current of a fourth pair of differential amplifiers to produce an output signal.
