Abstract

A Analog parallel processing-based Viterbi decoder which decodes PRML signal of DVD has been designed by CMOS circuit. The analog processing-based Viterbi decoder implements are functions of the conventional digital Viterbi decoder utilizing the analog parallel processing circuit technology. The Analog parallel processing-based Viterbi decoding technology is applied for the PR(1,2,2,1) signal decoding of DVD. The benefits are low power consumption and less silicon consumption. In this paper, the comparison of the Analog parallel processing-based Viterbi Decoder which has a function of the error correction between Max operation and Average operation is discussed.
