摘要： An inverter circuit includes: first to third transistors; and first and second capacity elements. The first transistor makes/breaks connection between an output terminal and a first voltage line in response to potential difference between an input terminal and the first voltage line or its correspondent. The second transistor makes/breaks connection between a second voltage line and the output terminal in response to potential difference between a gate of the second transistor and the output terminal or its correspondent. The third transistor makes/breaks connection between a gate of the second transistor and a third voltage line in response to potential difference between the input terminal and the third voltage line or its correspondent. The first and second capacity elements are inserted in series between the input terminal and the gate of the second transistor. A junction between the first and second capacity elements is connected to the output terminal.

摘要： An inverter circuit including: first to third transistors; first and second switches; and a first capacitive element. The first and second transistors are connected in series between a first voltage line and a second voltage line. The third transistor is connected between the second voltage line and a gate of the second transistor. The first and second switches are connected in series between a voltage supply line and a gate of the third transistor, and are turned on/off alternately to prevent the first and second switches from simultaneously turning ON. One end of the first capacitive element is connected to a node between the first and second switches. Off-state of the first transistor allows a predetermined fixed voltage to be supplied from the voltage supply line to the gate of the second transistor, via the first switch, the one end of the first capacitive element and the second switch.
