Abstract :
Performance of a partial response (PR) channel is usually reduced by noise correlation. Noise whitening is used to halve the complexity of an analog 1,7 code EEPR4 look-ahead detector to achieve performance comparable to that of a full Viterbi detector. The 0.8 /spl mu/m BiCMOS chip is a fully integrated read/write channel IC that operates in excess of 300 MSample/s (200 Mb/s). The 16.4 mm/sup 2/ 0.8 /spl mu/m BiCMOS chip dissipates 1.3 W at 200 Mb/s.
