Abstract: According to the Survey of WHO [World Health Organization] ,a people of about 285 million are visually impaired, 39 million are blind and 246 million are having low vision. Blindness is a serious ailment that makes people to suffer a lot. It occurs because of the eye related disorders like Retinitis Pigmentosa[RP], Age-Related Macular Degeneration[AMRD] and Glaucoma, resulting to lead an uncomfortable life style. Recent developments of the Biomedical Engineering field lead to the development of artificial human eye-Bionic eye analogous to natural eye. Bionic eye is a complex system which is integrated with many sub systems such as CCD camera, video processing unit, implantable chip , radio transmitter and receiver. The implanted artificial retina helps the patients of RP and AMRD regains the vision. Apart from this there exist limitations because of electrode count and noise levels. For better optimization to reduce noise levels of bio-potential signals an instrumentation amplifier is used. In this paper different Instrumentation amplifier are discussed.
Keywords: Differential Amplifier, CMRR(Common Mode Rejection Ratio), OP-AMP(Operational Amplifier).
