Abstract

In today's high-speed disk drive read channel ICs maximum likelihood detection using the Viterbi algorithm is a key component in reconstructing digital data sequences. The presented Viterbi decoder was realized in a 0.25-µm CMOS technology. Using the proposed comparison approach, it achieves a throughput rate of 550 Mb/s.
