Abstract

The present invention provides a level conversion circuit. The circuit is as follows: A cathode of a first equivalent diode is connected to a reference voltage, and an anode of the first equivalent diode is separately connected to a gate of a first switching transistor and a first end of a first capacitor; a second end of the first switching transistor and a first end of a second switching transistor are connected together; a second end of the second capacitor is separately connected to a cathode of a second equivalent diode and a gate of the second switching transistor; and a second end of the second switching transistor is grounded, and an anode of the second equivalent diode is connected to a reference voltage.
