Patent ID: 8710749

Claim:
A semiconductor device comprising: a first transistor; a load; a first wiring; a second wiring; a first switch; a second switch; a third switch; a fourth switch; a first capacitor; and a second capacitor, wherein the first switch is configured to select conduction or non-conduction between the first wiring and one of a pair of electrodes of the first capacitor, wherein the one of the pair of electrodes of the first capacitor is electrically connected to one of a pair of electrodes of the second capacitor, wherein the second switch is configured to select conduction or non-conduction between the other of the pair of electrodes of the first capacitor and one of a source and a drain of the first transistor, wherein the other of the pair of electrodes of the first capacitor is electrically connected to a gate of the first transistor, wherein the third switch is configured to select conduction or non-conduction between the one of the pair of electrodes of the first capacitor and the other of the source and the drain of the first transistor, wherein the other of the pair of electrodes of the second capacitor is electrically connected to the load, wherein the other of the source and the drain of the first transistor is electrically connected to the load, and wherein the fourth switch is configured to select conduction or non-conduction between the second wiring and the one of the source and the drain of the first transistor.
