Abstract
A transmitter pre-emphasis technique for copper
cable equalization is presented that is based on pulse-width
modulation (PWM). This technique is an alternative to the usual
2-tap symbol-spaced FIR (SSF) pre-emphasis. The technique
uses timing resolution instead of amplitude resolution to adjust
the filter transfer function, and therefore fits well with future
high-speed low-voltage CMOS processes. Spectral analysis and
time domain simulations illustrate that PWM pre-emphasis offers
more relative h
