Abstract:
Disclosed herein is a device that includes a capacitor, a pumping circuit supplying a pumping signal changed between first and second potential to a first electrode of the capacitor, and an output circuit precharging a second electrode of the capacitor to a third potential different from the first and second potentials. The second electrode of the capacitor is thereby changed from the third potential to a fourth potential higher than the third potential when the pumping signal is changed from the first potential to the second potential.
