Class AB amplifier circuit |
摘要 |
A class AB amplifier circuit includes a complementary output stage and a biasing circuit for biasing the output stage. The complementary output stage includes a P-type MOS transistor and an N-type MOS transistor, and the biasing circuit includes a bipolar transistor. The emitter and collector of the bipolar transistor are respectively connected to the gates of the P-type and N-type MOS transistors. The bipolar transistor is biased for controlling a bias voltage between the respective gates of the P-type and N-type MOS transistors.
