Abstract
This paper presents the architecture and circuit
design of a single chip 32 mm /5090 nm CMOS DSP transceiver
for electronic dispersion compensation (EDC) of multimode fibers
at 10 Gb/s, based on maximum likelihood sequence detection
(MLSD). This is the first MLSD-based transceiver for multimode
fibers and the first fully integrated DSP based transceiver for
optical channels reported in the technical literature. The digital
receiver incorporates equalization, Viterbi detection, channel es-
timation,
