WebNov 3, 2024 · DC PDN analysis is often ignored as part of digital systems design, but it is still important as modern digital systems supporting large ICs with many high speed IOs (such as FPGAs) will need to draw large bursts of current at any moment. To ensure noise-free power delivery, digital systems rely on AC power integrity analysis. AC PDN Analysis WebFigure 1: Generalized Test Setup for FFT Analysis of ADC Output . The spectral output of the FFT is a series of M/2 points in the frequency domain (M is the size of the FFT—the number of samples stored in the buffer memory).
