Obviously, such demand trickles down to every electrical interface in a network. Therefore, next-generation data centers need to evolve accordingly to accommodate the bandwidth demand of a rapidly changing world of technology. Since the channel loss is not improving at the same rate, most of the standards are adopting multilevel signaling to make more efficient use of the frequency spectrum. A 4"112Gb/s PAM-4 transmitter presented in this work is leading this trend to keep electrical signaling viable and
