In this video we are analyzing the transient response of two voltage regulators using an active load designed by Jim Williams and published in Application Note 133 by Linear Technology. The video covers the basics of feedback loops, a detailed analysis of the active load's schematic and some experiments. The PCB was designed by @GearAcquisitionSyndrome based on some improvements to Jim's original schematic.
