360 Mb/s (400 MHz) 1.1 W 0.35 /spl mu/m CMOS PRML read channels with 6 burst 8-20/spl times/ over-sampling digital servo

Rapid advances in giant magneto resistive (GMR) head technology will soon allow disk drive manufacturers to significantly increase both the linear and track density at the same time while maintaining acceptable error-rate performance. The steep increase in the linear density demands higher-performance and higher-data-rate partial response maximum likelihood (PRML) read channel electronics, while the increase in the track density demands higher-accuracy servo signal processing. A 360Mb/s CMOS partial response maximum likelihood (PRML) read channel for use in high-capacity low-power disk drive applications uses an industry-standard 0.35/spl mu/m one-poly-two-metal (1P2M) CMOS process technology.
