In-Circuit Design: Power Integrity-Power Distribution Network
Though signals tend to focus on impedance issues, the power distribution network (PDN) on the board is just as susceptible to impedance. The PCB layer stack up is a capacitor all its own. With the addition of bypass capacitors and inductors on the board, the ability to distribute power to avoid power starvation or reduce ripple becomes an integral part of the design.
The power distribution network and how impedances interrupt and starve components of the power they require.
Dive deeper into the impedances caused by capacitors and inductors, and more importantly, how they interact with each other.
How to manage the impedance by a careful selection of capacitors.
We will use the ICD PDN Planner tool to see the results as we present them visually.
