A bootstrap circuit includes: a first switch element, coupled a clock signal; a second switch element, coupled to an operating voltage and the first switch element; a third switch element, coupled to the first switch element; a first charge storage unit, coupled to the second and third switch elements; and a voltage converting unit, coupled to the first charge storage unit as well as the first, second and third switch elements. When the clock signal is at a first logic state, the first charge storage unit is charged. When the clock signal is at a second logic state, a cross voltage of the first charge storage ensures that the voltage converting unit converts an input voltage to an output voltage.
