ABSTRACT:
A level shifter that accommodates lower driving voltage of a driver circuit and has a sufficient capability of converting the amplitude of an input signal even when the voltage amplitude of the input signal is low is provided. A level shifter utilizing a current mirror circuit150and a differential circuit160is used in a portion for converting the voltage amplitude of the signal. Since the potential difference of a signal input through transistors105and106to the differential circuit120is amplified and outputted, the voltage amplitude can be normally converted without influence of the threshold of a transistor even when the voltage amplitude of the input signal is low.
