Abstract
It is an object of the present invention to provide a CMOS circuit implemented using four-terminal double-insulated-gate field-effect transistors, in which the problems described above can be overcome. Another object of the present invention is to reduce power consumption in a circuit unit that is in an idle state or ready state, i.e., to reduce static power consumption. The two gate electrodes of a P-type four-terminal double-insulated-gate field-effect transistor are electrically connected to each other and are electrically connected to one of the gate electrodes of an N-type four-terminal double-insulated-gate field-effect transistor, whereby an input terminal of a CMOS circuit is formed, and a threshold voltage of the N-type four-terminal double-insulated-gate field-effect transistor is controlled by controlling a potential of the other gate of the N-type four-terminal double-insulated-gate field-effect transistor.
