CHAPTER 4The Physical Basis of Resistance

The electrical description of every interconnect and passive device is based on using just three ideal lumped circuit elements (resistors, capacitors, and inductors) and one distributed element (a transmission line). The electrical properties of the interconnects are all due to the precise layout of the conductors and dielectrics and how they interact with the electric and magnetic fields of the signals.

Understanding the connection between geometry and electrical properties will give us insight into how signals are affected by the physical design of interconnects and feed our intuition about manipulating signal-integrity performance by design.
