Patent ID: 8183840

Claim:
A voltage converter, comprising: a first transistor, wherein a source terminal of the first transistor receives an input voltage, and a body terminal of the first transistor receives a first bias voltage; a second transistor, wherein the drain terminal of the second transistor is coupled to a drain terminal of the first transistor, a source terminal of the second transistor is coupled to a ground terminal, and a body terminal of the second transistor receives a second bias voltage; an inductor, wherein a first terminal of the conductor is coupled to the drain terminal of the first transistor, and a second terminal of the conductor generates an output voltage; a control module, coupled to a gate terminal of the first transistor and a gate terminal of the second transistor for controlling conducting states of the first transistor and the second transistor; a first bias voltage adjustment module, coupled between the body terminal of the first transistor and the control module and generating a first bias voltage; and a second bias voltage adjustment module, coupled between the body terminal of the second transistor and the control module and generating a second bias voltage, wherein the first bias voltage adjustment module and the second bias voltage adjustment module are controlled by the control module to adjust voltage values of the first bias voltage and the second bias voltage.
