Title

Analytical PDN Voltage Ripple Calculation using Simplified Equivalent Circuit Model of PCB PDN

Abstract

Printed circuit board (PCB) power distribution network (PDN) design performance depends on the peak voltage ripple caused by the integrated circuit (IC) switching currents. The input impedance seen by the IC looking into the PCB PDN can be calculated using a physics-based circuit model extracted from the cavity model approach. The input impedance is fitted to a simplified circuit model used to represent the PCB PDN. Using a switching current profile, the frequency domain noise voltage is found and transformed to the time domain ripple waveform which can then be used to evaluate the PDN design performance.
