Abstract
An inverter circuit for providing a high voltage output has an input terminal and an output terminal. The circuit further includes a first conductivity type first field effect transistor connected between a first power source line and the output terminal and having a gate electrode connected to the input terminal and second conductivity type second to (n+1)th field effect transistors connected in series between the output terminal and a ground line and having gate electrodes respectively connected to the input terminal. A voltage supply supplies (n-1) in number of second to (n)th power source voltages, whose absolute values become smaller in order, to a respective junction of the series connected second to (n+1)th transistors when the second to (n+1)th transistors are in OFF state.
