CMOS optical receiver for low power biomedical microsystems

In this paper, an integrated CMOS optical receiver in which optical power delivery and optical communication realized on a single channel is proposed. Pulse Width Modulation (PWM) method is applied on the light source for transmission of the signals. Clock, data and power signals are obtained by various filtering methods. The proposed receiver is designed in 180 nm UMC Standard CMOS technology and can operate with single integrated CMOS photodiode.
