CCD imagers for today’s consumer and commercial applications the emerging biomedical market presents new opportunities to CMOS APS. Prominent examples addressing distinct issues in life style and health care are the possibilities to restore vision through a sub-retinal CMOS imager implant and to fabricate a low-cost intracorporeal video probe through a miniature CMOS imager. Presented is the design and characteristics of the first CMOS imager chip that has been implanted into a patient’s eye with demonstration of partially-restored vision. Also presented and discussed are the design and characteristics of the first miniature APS imager chip based on Thin-Film-on-CMOS (TFC) photodiode technology targeted at low-cost and disposable diagnostic products. Both sensor designs exploit the High-Dynamic Range CMOS
