Voltage supply system for IC chips
 A voltage supply system for use on an IC chip is provided. The system comprises a voltage shifting circuit for transferring an IC chip external input voltage signal range to an operating voltage range of an IC chip internal logic circuit, an IC chip internal logic circuit including low voltage components contributing to major functions of the IC chip, a low voltage signal range to high voltage signal range conversion circuit for stretching the operating voltage signal range of the IC internal logic circuit to an IC chip external output signal range, and a reference potential signal generating circuit for generating reference potential signals.
