Abstract
A semiconductor device according to one embodiment includes first and second transistor columns which each include a NMOS transistor and a PMOS transistor which are connected in series between a first power wire and a second power wire. Further, a gate of the PMOS transistor of one transistor column is connected to a wire which connects the NMOS transistor and the PMOS transistor of the other transistor column. Furthermore, an AC signal obtained by superimposing a signal on a bias voltage which is a voltage lower than that of the gate of the PMOS transistor included in the same transistor column is supplied to the gate of the NMOS transistor included in the transistor column.
