Abstract
A half-duplex serial link design that is capable of
22 Gbps operation over PCB channels with up to 20 dB of loss is
presented. A current-mode transmitter can be con figured either as
a pre-cursor or post-cursor 2-tap FIR filter. The receiver consists
of a trans-admittance-trans-impedance single-stage linear equal-
izer that can provide 10 dB of high-frequency gain without the use
of peaking inductors. The CTLE is followed by an half-rate 2-tap
decision feedback equalizer with direct feedback. To m
