Abstract -A family of high-swing CMOS operational amplifiers has been developed to maximize the available dynamic range with low supply voltages. Complementary differential pairs are used to achieve an almost rail-to-rail input common-mode voltage range. High linearity is obtained by summing currents so that the small-signal differential-mode voltage gain is constant over the entire input common-mode voltage range.
