A LOW-POWER CONSUMPTION HIGH-VOLTAGE CMOS DRIVING CIRCUIT

摘要

A low-power consumption high-voltage CMOS driving circuit is directed to one kind of high-voltage driving circuit in the output driving circuit. There is an output buffer stage between the output terminal of the voltage-converting stage and the input terminal of the high-voltage output stage. The output buffer stage is composed of a high-voltage PMOS transistor and a high-voltage NMOS transistor. As the input terminal of the current stage output buffer unit, the gate of the high-voltage PMOS transistor is connected to the output terminal of the previous stage output buffer unit, the source of the high-voltage PMOS transistor is connected to power supply; The source of the high voltage NMOS transistor is connected to ground, the gate of the high-voltage NMOS transistor is used as the 3i sequential signal receiving terminal, The drains of the high voltage PMOS transistor and the high-voltage NMOS transistor are connected together as the output terminal of current output buffer unit which is connected to the input terminal of the next stage output buffer unit, the input terminal of the first stage output buffer unit as the input terminal of the output buffer stage is connected to the output terminal of the voltage-converting stage, the output terminal of the last stage output buffer unit as the output terminal of the output buffer stage is connected to another input terminal of high voltage output stage.
