622-Mb/s downlink transmission in a fiber-fed 60-GHz wireless system using a CMOS integrated optical receiver

A fiber-fed 60-GHz wireless system using a CMOS integrated optical receiver for broadband data transmission is demonstrated. The CMOS integrated optical receiver fabricated with 0.13-mum standard CMOS technology consists of CMOS-compatible avalanche photodetector, transimpedance amplifier, offset cancellation circuit, and output buffer. Downlink data transmission of 622-Mb/s BPSK data signals in the 60-GHz band is successfully demonstrated with BER less than 10
^-9
at the incident optical power of -4 dBm.
