With the development of mobile network technology, HTTP mobile steaming is deployed by most of the video websites. Thus a lot of research works have been done on the Quality of experience (QoE) evaluation for HTTP mobile streaming. However, in most of them, only the factors in the network layer was considered, and the important information about user dissatisfaction with the video quality may be ignored...
Monolithic power management integrated circuit chips are widely used in both consumer products and industrial products. In some applications the load changes drastically. A 2MHz integrated synchronous Buck converter is designed to manage the dynamic load for these applications. The current mode control and active voltage positioning are employed to achieve high transient performance at pulse load...
The series resonant dc–dc converter with clamped capacitor voltage exhibits excellent characteristics in forward operating mode, including simple control, high reliability, soft switching, high power density, and inherently limited load fault current. However, the conventional single angle phase-shift modulation that works well in the forward mode cannot reverse the power flow. In this paper, we propose...
A rising horizon in chip fabrication is the 3D integration technology. It stacks two or more dies vertically with a dense, high-speed interface to increase the device density and reduce the delay of interconnects across the dies. However, a major challenge in 3D technology is the increased power density which brings the concern of heat dissipation within the processor. High temperatures trigger voltage...
