Abstract
We demonstrate a new CMOS synchronized photoreceiver for conversion of optical input pulses to digital output signals. A combination of two p-n-p vertical CMOS BJTs controlled by an external clock is designed to achieve the first clocked photoDarlington structure. This clocked photoDarlington is used as a detector of input light. The generated photocurrent is reflected by a current-mirror comparator and digitized by a buffer. The synchronized photoreceiver, in its return-to- zero (RZ) format, has been implemented in a standard digital 0.7-micrometer, 5-V n-well CMOS technology with an effective area of 100 X 60 micrometer2. It was measured to operate at 100 MHz with an external input light of -18.8 dBm/beam.
