Abstract
A body bias voltage generating circuit for supplying a body bias voltage to a body of a transistor of a functional circuit is provided, including: a first transistor and a second transistor connected in series between a supply voltage terminal and a ground terminal, wherein a control terminal of the first transistor is coupled with a control terminal of the second transistor; a third transistor, wherein a body of the third transistor is electrically coupled with any one of the body of the first transistor and the second transistor, and a terminal of the third transistor is coupled with the body of the third transistor; and a resistance element coupled between the terminal of the third transistor and a current input terminal of the first transistor or a current output terminal of the second transistor. The terminal of the third transistor is the body bias voltage.
