Design of Equalizer Chip for High-Density Hard Disk Drive Read Channel
초록
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.
