Impact of Channel Loading to Power Distribution Network Designs

摘要

A PDN consisting of lumped elements is passive and linear to the frequency variation. However, adding active drivers to the PDN is easily distorted depending on load conditions at the end of a signal channel. Depending on two major states in a push-pull driver, pull-up versus pull-down, the load affects the passive PDN, resulting in a non-linear PDN profile. This non-linearity is demonstrated in this paper of the first time. We investigate the non-linear behavior for various signaling schemes in both frequency and time domains along with different load conditions.
