Abstract
There is disclosed a substrate bias circuit including an oscillation circuit oscillating at a predetermined frequency; a control signal generation circuit operative to generate a control signal for changing, on the basis of an output from the oscillation circuit, a substrate potential in a direction to ensure a threshold level of a transistor so that it becomes greater; and a charge pump circuit including a capacitor and operative to control discharge of the capacitor by said control signal to thereby change the substrate potential.
