Abstract
A new adaptation strategy of I/O link equalizers is
presented based on minimizing the bit error rate (BER) as the
objective function to maximize the receiver voltage margin. The
adaptation strategy is verified in a 90-nm test chip on both the
transmitter finite-impulse response filter (Tx-FIR) and the receiver
decision-feedback equalizer (Rx-DFE). The performance is com-
pared with the commonly used sign-sign least mean square (SS-
LMS) adaptation and demonstrates significant improvements es-
