Summary
As demonstrated in this paper, transmission line behavior can be accurately modeled using simple SPICE simulations
in an LC network. A better understanding of transmission line behavior is important for achieving proper
impedance matching and proper termination to minimize loss from reflections and also to maximize signal integrity.
In addition, a deeper understanding of transmission lines will enable you to better understand and interpret results
from signal integrity tools, such as those in the Cadence
