摘要: A multipath nested structure which overcomes the bandwidth reduction in conventional by appending an independent feedforward path for high frequencies is presented. At low frequencies, opamp behaves as a three-stage Miller-compensated amplifier, while at has nature and of two-stage amplifier with simple pole splitting. In this fashion, concept circumvents classical DC-gain/high-frequency-performance dilemma. No pole-zero doubles occur, because two regions operation can be independently closely matched, unaffected variations parameters IC process fabricated. >
