Abstract
In this paper, we present a programmable intraocular pressure sensor system implant integrated on a single CMOS chip, It contains an on-chip micromech anical pressure sensor array, a temperature sensor, readout and calibration electronics, a CIC-based digital control unit, and an RF transponder. The transponder enables wireless data transmission and wireless power reception , thus making batteryless operation feasible. The chip has been fabricated in a 1.2-mum n-well CMOS process complemented by additional processing step s.
