Abstract
A Silicon-On-Insulator (SOI) CMOS circuit comprises a plurality of PMOS transistors connected in series to each other, each of the plurality of PMOS transistors having its body and gate connected to each other, and at least an NMOS transistor connected to one of the plurality of PMOS transistors, the NMOS transistor having its body connected to a low reference potential having a value of ground. The SOI CMOS circuit can further comprise a plurality of potential limiting circuits each connected between the body and gate of each of the plurality of PMOS transistors, for setting a lower limit of the potential of the body of each of the plurality of PMOS transistors to a voltage between a high reference potential and a potential obtained by subtracting a built-in potential from the high reference potential.
