Class AB CMOS output stage for operational amplifier |
摘要 |
A class AB CMOS output stage for an operational amplifier with a rail-to-rail output swing includes a pair of complementary control transistors connected in opposing phase to each other. Connection of the complementary control transistors is made between driving nodes of a pair of complementary output transistors driven by a differential signal. The differential signal is provided by a pair of differential signal input lines connected to an input stage of the operational amplifier. Biasing of the pair of complementary control transistors is by the differential signal.
