Abstract
A voltage switch circuit uses PMOS transistors to withstand high voltage stress. Consequently, the NMOS transistors are not subject to high voltage stress. The lightly-doped PMOS transistors are compatible with a logic circuit manufacturing process. Consequently, the voltage switch circuit may be produced by a logic circuit manufacturing process.
