A phase and base potential converter according to the invention is constructed as follows. Two MOS transistors having the same size and characteristic are connected in series between a first power supply and a second power supply, a gate of one MOS transistor is served as an input terminal of a voltage based on the first power supply, and a source of the other MOS transistor is served as an output terminal of a voltage based on the second power supply. One of the first power supply or the second power supply is a lower potential power supply, and the other is a higher potential power supply. The phase and base potential converter being thus constructed makes it possible to convert, for example, a signal based on the Vss into a signal based on the Vdd and thereby synthesize signals having different base potentials.
