Abstract
A CMOS image sensor for spatial optical communication is presented. A two-transistor optical communication cell with a depleted photodiode and lateral charge overflow drain improves the light pulse response. A weighed summation of 9-point parallel analog outputs and pulse-equalizing technique greatly enhance the bit-rate and communication distance up to 10 Mb/s and 70 m, respectively.
