Abstract

Design techniques for realizing analog switch and rail-to-rail constant g<inf>m</inf> opamp with approximately twice the standard supply voltages and signal swings are proposed in this paper. Based on these techniques, a 6V stimulation monitoring circuit for monitoring 8 different stimulator outputs was implemented in a conventional 0.18&#x00B5;m CMOS process using standard 3.3V I/O devices. Maximum on-resistance for the switches was less than 3.15k&#x2126; and the variations on the opamp input g<inf>m</inf> values were less than &#x00B1;2.9% with a current consumption of 20&#x00B5;A at 6V.
