Inductive Cross-talk within IC Packaging is becoming a significant bottleneck in high speed inter chip communication. So the off-chip drivers typically source and sink 10 to 1000 drive internal loads. Thus simultaneously switching many off-chip drivers can cause large power (VDD) and ground current surges. These changes in current flow induce a voltage drop on the drivers’ local VDD rail and a ...
