Power amplifier in bicmos technology having an output stage in MOS technology

摘要

The present invention relates to a power amplifier having an output stage in MOS technology, including an upper half-output stage comprised of two P-channel MOS power transistors mounted as a current mirror, a lower half-output stage comprised of two N-channel MOS power transistors mounted as a current mirror, an output terminal of the amplifier corresponding to the common drains of a first MOS transistor of the upper stage and of a first MOS transistor of the lower stage, and a control stage in bipolar technology for setting, according to a control voltage, two control currents of the half-output stages.
