[A1-1] 12.5-Gb/s Monolithically Integrated Optical Receiver With CMOS Avalanche Photodetector
نویسندگان
چکیده
We present a 12.5-Gb/s monolithically integrated optical receiver with CMOS avalanche photodetector (CMOS-APD) realized in 65-nm CMOS technology. The optical detection bandwidth limitation of CMOS-APD due to the carrier transit time is compensated by underdamped TIA. With this optical receiver, 12.5-Gb/s 850-nm optical data are successfully detected with bit-error rate less than 10 at the incident optical power of 2 dBm. The fabricated optical receiver has the core size of 0.24 × 0.1 mm and its power consumption excluding output buffer is about 13.7 mW with 1.2-V supply voltage. Keywords—Avalanche photodetectors (APDs); Monolithic integration; Optical interconnects; Optical receiver;

An optical receiver using a CMOS-compatible avalanche photodetector (CMOS-APD) is demonstrated. The CMOS-APD is fabricated with 0.18 μm standard CMOS technology and the optical receiver is implemented by using the CMOS-APD and a transimpedance amplifier on a board. The optical receiver can detect 6.25-Gb/s data with the help of the series inductive peaking effect.
