A reconfigurable power management structure for inductive power delivery has been proposed by adaptively employing either resonant voltage or current mode (VM or CM) to improve the inductive power transmission performance against coils’ coupling distance (d), orientation ($\phi $ ), and load impedance (RL) variations. At the presence of these variations, unlike conventional VM and CM power managements...
Future naval medium-voltage direct current (MVDC) power systems will contain a large number of power electronic devices. The switching events from these devices will produce undesirable effects, such as common-mode (ground) current through coupling of the power system and the ships hull. Historically, research in the area of electromagnetic characterization provides insight into common-mode and conduction...
Higher density, tighter margin and lower cost power solutions for the cutting edge datacenter require more characterization of voltage regulator (VR) beyond its power conversion performance such as voltage ratio and efficiency. Fast transient, ground noise sharing and high frequency switching noises coupling to high speed IO are some of the technical aspects that need to be predicted and designed...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
