Voltage Drops across Traces and Vias
With today’s low impedance circuits, voltage drops may introduce an unacceptable amount of noise or signal level uncertainty into a circuit, leading some designers to avoid the use of vias on boards altogether. How to predict the
voltage drop across a trace, and why the voltage drop across a via is almost negligible by comparison.
