Abstract
A triple-resonance LC network increases the bandwidth of cascaded differential pairs by a factor of 2/spl radic/3, yielding a 40-Gb/s CMOS amplifier with a gain of 15 dB and a power dissipation of 190 mW from a 2.2-V supply. An ESD protection circuit employs negative capacitance along with T-coils and pn junctions to operate at 40 Gb/s while tolerating 700-800 V.
