Abstract:
1. A level conversion circuit, comprising: a first level shifter, converting a first control voltage into a second control voltage during a voltage conversion period, wherein the first control voltage is between a first voltage and a second voltage, and the second control voltage is between a first middle voltage and a second middle voltage; and a second level shifter, coupled to the first level shifter and converting the second control voltage into a third control voltage during the voltage conversion period to control a next stage circuit, wherein the third control voltage is between the first middle voltage and a third voltage, wherein the first level shifter detects the third voltage and generates a plurality of middle voltages based on a detection result, the middle voltages comprise the first middle voltage, the second middle voltage, and a third middle voltage, and the second level shifter generates the third control voltage based on the middle voltages.
