摘要

A novel CMOS synchronized photoreceiver is proposed for conversionnof optical input pulses to digital output signals. The photoreceiverncircuit consists of a photoDarlington used as a detector of input lightnfollowed by a current-mirror comparator used as a converter tonelectronic signals. A combination of two p-n-p vertical CMOS bipolarnjunction transistors controlled by an external clock is designed tonachieve the first clocked photoDarlington structure. The generatednphotocurrent is amplified and digitized by the current-mirror comparatornin a return to-zero format. The synchronized photoreceiver has beennimplemented in a standard digital 0.7 Μm, 5 V n-well CMOS technologynwith an effective area of 100×60 Μm2. It wasnmeasured to operate at 100 MHz with an external input light of 13.3nfJ/pulse (-18.8 dBm/beam)
