Abstract
A digital signal processor for a PRML system includes: an NMOS pass transistors gain control circuit responsive to a digital data signal for adjusting the gain of the digital data signal; an NMOS pass transistor phase control circuit responsive to the digital data signal for adjusting the phase of the data signal; and an NMOS pass transistor Viterbi maximum likelihood detector circuit for determining the most probable sequence of symbols in the data signal.
