A compact, low-power-consumption 5-Gbps OEIC receiver without equalizer fabricated in 0.18-µm CMOS technology

A low-cost, compact 5-Gbps fully integrated CMOS optical receiver without equalizer is fabricated in this paper in a standard 0.18-μm CMOS technology. The measured responsivity of the DNW-strip-SMPD operating in avalanche mode is 1.4A/W, while the bandwidth is 2.9GHz with 11.6V reverse bias voltage. The application for 5-Gbps very-short-reach optoelectronic integrated circuit (OEIC) receiver with a bit-error rate <10−12 at incident optical power of −4 dBm has been experimentally demonstrated. The core chip area of the OEIC receiver is 0.736mm by 0.515mm, and it consumes 96mW from the 1.8V supply. Our OEIC receiver has the smallest area and the lowest power consumption in the OEIC receivers reported so far fabricated in 0.18-μm CMOS technology.
