A high-frequency fully differential BiCMOS operational amplifier

A high-frequency fully differential BiCMOS operational amplifier design for use in switched-capacitor circuits is presented. The operational amplifier is integrated in a 3.0-GHz, 2- mu m BiCMOS process with an active die area of 1.0 mm*1.2 mm. This BiCMOS op amp offers an infinite input resistance,...
