Power - reliability tradeoff in low power 4-PAM signaling in on-chip communication

The higher data rates at low power consumption have recently directed attentions towards on/off-chip multilevel signaling. However, its tighter noise margin cost leads to reliability concern. In this work, the reliability issue for multilevel signaling is highlighted using 4-PAM scheme. Three cost-e...
