Abstract
A level conversion circuit includes level conversion portions which are connected in series. The level conversion portion includes circuit blocks. The circuit block inverts an input signal. The circuit block includes a transistor connected between a power supply and a node, a transistor connected between the node and a power supply, a transistor connected between a gate of the transistor and the power supply, and a capacitor connected between an output node and the gate of the transistor. The circuit block carried out level conversion in step with operation of the transistor in accordance with a signal applied from an input node to a gate thereof and operation of the transistor an ON/OFF state of which is switched by application of an output of the circuit block to a gate thereof, to thereby output potential change at the node.
