Abstract:
An operation speed of a voltage conversion circuit is improved without increasing an output level of the voltage conversion circuit. The voltage conversion circuit is provided with a high-voltage side transistor and a gate control unit. In this voltage conversion circuit, the high-voltage side transistor outputs a predetermined high voltage higher than a predetermined reference voltage. Also, in the voltage conversion circuit, the gate control unit generates a predetermined control voltage higher than a predetermined high voltage from an input signal and applies the same between a gate and a source of the high-voltage side transistor, thereby allowing the high-voltage side transistor to output a predetermined high voltage.
