WIPO Patent Application WO/2018/171249
Kind Code:
A1
Abstract:
Disclosed is a level shift circuit, comprising: an input circuit and a shift circuit. The input circuit is configured to carry out inversion and delay operations on input level signals to obtain a first level signal, a second level signal, a third level signal, and a fourth level signal. The rising edge of the first level signal is earlier than the falling edge of the second level signal by a first preset time, and the falling edge of the first level signal is later than the rising edge of the second level signal by a second preset time; the third level signal is a signal obtain by delaying the first level signal by a third preset time, and the fourth level signal is a signal obtain by delaying the second level signal by a fourth preset time; the first preset time is longer than the third preset time, and the second preset time is longer than the fourth preset time. The shift circuit is configured to output a first voltage signal and a second voltage signal according to the level signals. Also disclosed is a level shift method.
