Abstract:
A level shift circuit comprising:a level shifter section, having an input signal and an inversion input signal formed by inverting the high/low level of the input signal inputted thereto, with a first voltage that is a high power-supply voltage and a second voltage that is a low power-supply voltage being connected thereto, which, based upon the high/low level of the input signal and inversion input signal, switches the first voltage and the second voltage to output the resulting voltage; an inversion input signal generation section, having the input signal, either of the first voltage and the second voltage, and a third voltage that gives an output level corresponding to the low level or the high level of the inversion input signal, inputted thereto, which, based upon the high/low level of the input signal, switches the output voltage level so as to generate an inversion input signal formed by inverting the input signal; and a voltage-dividing section which voltage-divides and extracts the third voltage between the first and second voltages.
