Abstract

The invention provides a level shift circuit, an integrated circuit and electronic equipment. The level shift circuit comprises an input module used for outputting a first control signal according to a received first power supply voltage signal, a first input voltage, a second input voltage, an anti-phase voltage of the first input voltage and an anti-phase voltage of the second input voltage; the control voltage generation module is used for receiving the first control signal and generating a plurality of node voltages according to the first control signal and the second power supply voltage signal; the output control module is used for generating a first output signal, a second output signal, a third output signal and a fourth output signal according to the node voltage and a first power supply voltage signal; or a fifth output signal, a sixth output signal, a seventh output signal and an eighth output signal are generated according to the second power supply voltage signal and the node voltage.

Description

technical field [0001] The present application relates to the technical field of semiconductors, and in particular, the present application relates to a level shift circuit, an integrated circuit, and an electronic device. Background technique [0002] The level shift circuit is the "conversion interface" between the low-voltage circuit and the high-voltage circuit. The low-voltage signal is converted into a high-voltage signal through the level shift circuit, and the control of the low-voltage logic input stage to the high-voltage logic output stage is realized. It is useful in display drive and flash memory. Wide range of applications. [0003] When a low-voltage signal is converted into a high-voltage signal by a traditional level shift circuit to drive a transistor switch in a digital-to-analog converter (DAC, Digital to Analog Converter), the traditional level-shift circuit can only convert a low-voltage signal into a high-voltage signal. The signal does not have the p...
