A Complementary CMOS differential amplifier has automatic operating point adjustment (self-biasing) and the properties of a rail-to-rail amplifier. The CMOS differential amplifier uses folded cascodes and is considerably faster in operation than previous CMOS differential amplifiers, since it comprises a circuit element that ensures that, during the operation of the CMOS differential amplifier, all MOS FETs of the cascodes operate in their saturation range (that is not in their resistive range). The CMOS differential amplifier may be used in an input stage, a signal distribution circuit and a clock pulse distribution circuit.
