METHOD AND APPARATUS FOR CHARACTERIZING POWER SUPPLY IMEPDANCE FOR POWER DELIVERY NETWORKS

摘要

A method and apparatus for generating an arbitrary current waveform for use in characterizing power supply impedance for power delivery networks are provided. The method begins by providing an arbitrary waveform as an input to a test circuit. The current and voltage at an output of a device under test in then examined. A frequency is then swept through a pre-determined range; and the frequency of the arbitrary voltage waveform is changed to match a predetermined frequency and impedance point.
