Reduction in the area of a high voltage multiplexer

A high-voltage 16-channel, 16-bit settling, multiplexer is proposed with reduced area and better Total Harmonic Distortion (THD) and Crosstalk. Every conducting switch in this multiplexer is capable of handling +/−12V input with a constant low resistance across the entire input voltage range using a boosted-gate technique with +/−15V power supply to have better THD. The proposed multiplexer is simulated using 0.6um high-voltage thick-gate CMOS technology and verified through extensive spectre simulations. Layout was drawn and back-annotated simulations were done to verify its working.
