Abstract
An energy-efficient (1.02 pJ/b) and high-speed
(20.83 Gb/s/wire, 417 Gb/s/mm) link for ultra-short reach (USR)
applications (up to 6-dB channel loss at the Nyquist frequency
of 12.5 GHz) is presented. Correlated non-return to zero (CNRZ)
signaling with low sensitivity to inter-symbol interference (ISI)
has been developed to improve the link budget. In addition to high
pin efficiency (5b6w: 5 bits over 6 wires), the proposed signaling
method provides very good resistance against common-mode and
