Abstract

By fabricating a discrete cell photodiode with multiple edge contacts, and allowing for operation under two different current sensing schemes, a diode which operates optionally as either a continuous or discrete cell position sensitive photodetector has been realized. Inclusion of on-chip CMOS switching circuitry enables a user of such a photodetector to change its operating mode by the use of a single digital input line. Experimental results of the dual mode photodiode with switching circuitry are presented in this paper.
