ABSTRACT:
A Bi-CMOS circuit includes a bipolar output stage and a CMOS circuit. The bipolar output stage includes pull-up and pull-down transistors which form an output end. The CMOS circuit receives an input signal and generates a signal for driving the output stage. The CMOS circuit comprises a CMOS inverter for receiving the input signal, a p-channel MOS transistor for driving the pull-up transistor of the bipolar output stage based on the input signal, an n-channel MOS transistor for driving the pull-down transistors of the bipolar output stage based on the input signal, a p-channel MOS transistor for discharging a base of the pull-up transistor based on an output of the CMOS inverter, and an n-channel MOS transistor for discharging a base of the pull-down transistor based on an output of the CMOS inverter.
