Abstract
To meet stringent electromagnetic interference
(EMI) requirements in modern integrated systems, this article
presents a gallium nitride (GaN)-based switching power converter
operating at 8.3 MHz. It employs a Markov continuous ran-
dom spread-spectrum modulation (RSSM) technique to spread
EMI spectra almost uniformly, and thus attenuate EMI level
effectively. On the other hand, a one-cycle
ON-time rebalancing
scheme is designed to stabilize the duty-ratio of the converter
even if the switching f
