Abstract
The gate terminals of several Pch transistors are connected to an output terminal and controlled with second and third potentials. The gate terminals of several Nch transistors are connected to the output terminal and controlled with first and fourth potentials. In this way, an input signal between a VDD potential and a GND potential can be level-shifted to an output signal between a VPP potential and a VBB potential with a simple circuit structure. Also, the operation speed in switching potentials can be improved.
