INTEGRATED AMPLIFIER IN CLASS AB IN CMOS TECHNOLOGY

摘要

The invention relates to an amplifier integrated in CMOS technology. This amplifier, working in class AB, comprises an output stage comprising an NPN T-bipolar transistor and an NT-channel transistor MOS transistor, mounted in series. IN THE MANNER OF A "PUSH-PULL" STAGE. / P P THE NPN TRANSISTOR IS DIRECTLY CONTROLLED ON ITS BASE BY THE SIGNAL TO BE AMPLIFIED. THE TRANSISTOR MOS T RECEIVES THE DIFFERENTIAL AMPLIFIER OUTPUT SIGNAL ON ITS CONTROL GRID, THE INPUTS OF WHICH ARE CONNECTED TO THE OUTPUT OF THE AMPLIFIER AND TO THE TRANSMITTER E OF ANOTHER BIPOLAR TRANSISTOR RECEIVING ON ITS BASIS THE SIGNAL TO BE AMPLIFIED. / P P APPLICATION: INTEGRATED AMPLIFIERS CAPABLE TO EXIT NOTAMENT ON A NORMALIZED CHARGE OF 600O. / P
