ABSTRACT:
A voltage generating circuit outputs a generated voltage corresponding to (a+b+c)-bit digital data from a plurality of generated voltages. The voltage generating circuit includes a first selector of each conductive type and 2apieces of second selectors of each conductive type. Each first selector is constituted by the conductive type MOS transistor, and based on upper order a-bit of the digital data, outputs one of the generated voltages selected corresponding to low order (b+c)-bit of the digital data. Each second selector is constituted by the conductive type MOS transistor, and based on low order a-bit of the digital data, outputs one of the generated voltages to the first selector of the conductive type. One output and the other outputs of the first selectors of both conductive types are connected to one another.
