Abstract
A level shift circuit includes a level shift module and a voltage comparing module. The level shift module includes a plurality of stages of level shift units, each including a front-end circuit and an inverter circuit. The inverter circuit is electrically coupled to the front-end circuit and receives and inverts an output signal of the front-end circuit. The front-end circuit receives a clock signal, converts high/low voltage level of the clock signal into first/second voltage level, respectively, and outputs a respective signal with the first/second voltage level. The voltage comparing module is coupled to the level shift module and receives output signals of the inverter circuit of the first level shift unit and of the front-end circuit in the second level shift unit and compares the two output signals. The voltage comparing module outputs a short-circuit protection trigger signal when the two output signals have different voltages.
