Figure 1 – Accumulated jitter

The most common way to evaluate a power distribution network is to look at its impedance over the effective frequency range. A lower impedance will produce less noise when transient current is demanded by the IC output buffers. However, this transient current needs to be provided at the same time for each transition or jitter will… Read More
