Not All Jitter is Created Equal: Understanding Jitter in Switching Power Supplies
A tutorial discussion on jitter in switching DC-DC converters. Not all power supply designs are equally susceptible to jitter, nor are they equally affected by jitter. Modes of switching jitter are defined and explained for several popular control architectures, which are then analyzed for sources of jitter. An example contrasting the amount of jitter and effect on output voltage caused by this jitter is included, using a closed-loop time domain simulation.
