摘　　要：A high-scale integrated optical receiver including a preamplifier, a limiting amplfiaer, a clock anO data recovery （CDR） block, and a 1：4 demultiplexer （DEMUX） has been realized in a 0.25 p,m CMOS technology. Using the loop parameter optimization method and the low-jitter circuit design technique, the rms and peak-topeak jitter of the recovered 625 MHz clock are 9.4 and 46.3 ps, respectively, which meet the jitter specifications stipulated in ITU-T recomnaendation G.958. In response to 2.5 Gb/s PRBS input data （223-1）, the recovered and frequency divided 625 MHz clock has a phase noise of -83.8 dBc/Hz at 20 kHz offset and the 2.5 Gb/s PRBS data has been demultiplexed into four 625 Mb/s data. The power dissipation is only 0.3 W under a single 3.3 V supply （excluding output buffers）.A high-scale integrated optical receiver including a preamplifier, a limiting amplfiaer, a clock anO data recovery （CDR） block, and a 1：4 demultiplexer （DEMUX） has been realized in a 0.25 p,m CMOS technology.
