【 摘 要 】

A power distribution network (PDN) is designed to provide clean power and facilitate high signal integrity in modern electronic systems. However, the design of a good PDN has faced challenges due to increased number of voltage rails in a design, stringent low noise requirement, and increased electromagnetic coupling and crosstalk among different parts of the circuits. Current power delivery method mostly utilizes voltage and ground plane pairs. This approach; however, suffers from return path discontinuity issues that can lead to signal integrity issues such as worsened simultaneous switching noise and ground bounce. The objective of this dissertation is to use a recently proposed new PDN design by using power transmission lines (PTL) to replace voltage planes for high speed I/O signaling. The PTL based design is shown through simulation and measurement to provide good power and signal integrity for high speed I/Os operating in the gigabits per second data rate in complex electronic systems. The PTLs also produces better broadband electromagnetic isolation between signaling and power distribution networks as compared to that in the current voltage-ground plane based approach.
