ABSTRACT:
A low leakage CMOS analog switch circuit comprising conventional MOS switches having transistors of high threshold voltages coupled to an interface circuit comprising transistors of low threshold voltages is provided. The N-channel threshold voltage of transistors in the switches is adjusted upward and the P-channel threshold voltage of transistors in the interface circuit is adjusted downward through the use of a single mask in one process step.
