Thermal Impact of Using a Band-limited, Linear Regulator in 120 A/ns Transient Suppression for Future Microprocessor Power Systems

摘要

Impedance analysis is used to demonstrate the usefulness of a bandpass-limited linear regulator in improving load regulation of ±120 A/ns transitions at 100 MHz pulse rate. The utility of the linear regulator is compared against the thermal cost, with special attention given to the issue of parasitics, by means of simulations.
