초록

A parallel analog Viterbi decoder which decodes PR (1,2,2,1) signal of optical disc has been fabricated into chip. The proposed parallel analog Viterbi decoder implements the functions of the conventional digital Viterbi decoder utilizing the analog parallel processing circuits. In this paper, the analog parallel Viterbi decoding technology is applied for the PR signal. The benefit of analog processing is the low power consumption and the less silicon consumption. The test results of the fabricated chip are reported in this paper.
