Power Integrity with Voltage Ripple Spectrum Decomposition for Physics-Based Design
A decomposition method for the PCB PDN voltage ripple caused by the IC switching current is developed based on an equivalent circuit model from a cavity model. The decomposition is presented both in frequency domain and time domain. Along with this decomposition approach, a one-to-one correspondence between the voltage ripple and the geometry is revealed. Guidelines to decrease the PCB PDN voltage ripple is also discussed and corroborated by both simulation and analytical calculation.
