Two CMOS differential amplifiers, one that is intended for applications in which the input common-mode range is relatively limited, the complementary self-biased differential amplifier (CSDA), and one that is intended for applications in which the input common-mode range is bounded only by the supply voltages, the very-wide-common-mode-range differential amplifier (VCDA), are discussed. Both differ from conventional CMOS differential amplifiers in having fully complementary configurations and in being self-biased through negative feedback. The amplifiers have been applied as precision high-speed comparators in commercial VLSI CMOS integrated circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
