ABSTRACT:
Provided is a voltage level shift circuit including: a first voltage level shift circuit formed of a P-channel enhancement type transistor (M1) and an N-channel depletion type MOS transistor (M3); and a second voltage level shift circuit formed of a P-channel enhancement type transistor (M2) and an N-channel depletion type MOS transistor (M4). In the voltage level shift circuit, a cascode circuit using an N-channel depletion type transistor (M5) is serially connected to the first voltage level shift circuit, a cascode circuit using an N-channel depletion type transistor (M6) is serially connected to the second voltage level shift circuit, and a unit for complementarily controlling bias voltages of the respective cascode circuits. As a result, an output signal of the voltage level shift circuit connected to an input of a differential amplifier circuit, for expanding an input voltage range of a signal, is not affected by fluctuations in power supply voltage.
