Design of Equalizer Chip for High-Density Hard Disk Drive Read Channel
대용량 하드디스크 드라이브 읽기 채널을 위한 이퀄라이저 칩의 설계
Abstract
This paper describes design of equalizer chips of the read channel for high-density hard-disk drives. In order to meet increasing need of hard-disk drives, the read channel incorporates various PRML schemes. They require proper equalization to implement the efficient hardware of Viterbi decoders. This paper describes EPR-IV equalization for the read channel and a 200MHz analog FIR filter chip is presented which utilizes the sampled analog signal processing efficiently.
