A voltage supply circuit including: first and second nodes; a predetermined potential; and an output transistor having its control terminal connected to the first node, its first terminal connected to the second node and its second terminal connected to an output terminal. The circuit further includes: a switching element which turns on in response to an active reset signal to connect the potential and the first and second nodes together; a first capacitor connected to the first node and supplied with a clock; a second capacitor connected to the second node and supplied with another clock; and an adjustment section adapted to adjust the clock amplitudes so that the potentials of the first and second nodes vary with a predetermined difference maintained therebetween. The reset signal is basically reverse in phase to the clocks.
