Design of 250 Mb/s 10-channel CMOS optical receiver array for computer communication

Abstract

This paper describes design of 250 Mbps 10-channel CMOS optical receiver array for computer communication using the general-purpose CMOS technology. It is one of the most important building blocks for parallel optical interconnection system. The receiver array consists of the photo-detectors, amplifier chains and phase-locked loop for data recovery. The chip was fabricated in a 0.65 /spl mu/m 2-poly, 2-metal CMOS technology and dissipates 330 mW for one-channel and 70 mW for PLL for /spl plusmn/2.5 v supply.
