ABSTRACT:
A CMOS driving circuit, wherein an output buffer stage with a transistor switch is added to the final buffer stage of a conventional CMOS driving circuit to drive a power transistor. The output buffer stage has two input terminals for DC input voltage, and uses the high voltage of a voltage converting circuit in a multi-voltage system as one DC input voltage. The driving load capacity of the CMOS driving circuit is improved by converting the higher of the two DC input voltages to a modulated driving voltage and outputting it via an output terminal, so that the on-resistance of a power transistor connected with the output buffer stage is lowered, the power consumption of the power transistor is reduced, the output capacity is improved, and the area of the power transistor is lowered with the same output power.
