ABSTRACT:
A boost circuit comprising a first level shifter and a switch circuit is provided. The first level shifter outputs either an output voltage of the boost circuit or a first bias voltage according to a boost control signal. The switch circuit determines whether to transmit a second bias voltage to an output terminal of the boost circuit according to the output of the first level shifter. The present invention further comprises a capacitance equivalent circuit and a second level shifter. The capacitance equivalent circuit comprises a first terminal and a second terminal, and the first terminal is electrically coupled to the output terminal of the boost circuit. Similarly, the second level shifter outputs a third bias voltage or the first bias voltage to the second terminal of the capacitance equivalent circuit. In addition, the first bias voltage is smaller than the second bias voltage and the third bias voltage.
