This paper presents multi-step capacitor switching methods for SAR ADCs based on precharge with floating capacitors and charge sharing. The proposed switching methods further reduce the transient power of the split monotonic switching method (an improved version of the monotonic switching method). Compared to the split monotonic switching, adding charge sharing achieves around 50% reduction in ...

Multilevel inverter has so many advantages than conventional two level inverter. As the number of level increases the output approaches to a pure sinusoidal wave.Multilevel inverter using both fundamental frequency switching and higher frequency switching. In this paper discuss only about higher frequency switching.In higher frequency switching we are using two signals, one is reference signal ...

A new large-signal nonlinear control technique is proposed to control the duty-ratio d of a switch such that in each cycle the average value of a switched variable of the switching converter is exactly equal to or proportional to the control reference in the steady-state or in a transient. One-Cycle Control rejects power source perturbations in one switching cycle; the average value of the swit...

This paper presents a fuzzy logic approach for switching multiple reference models, within the Model Reference Adaptive Control (MRAC) framework, in response to major changes in the plant operating conditions. Following a rule base, the fuzzy switching scheme effectively monitors changes in operating conditions or such drastic changes in plant. A fuzzy inference engine then fires appropriate ru...

The free viewpoint switching is one of the most important features of multi-view video streaming. The key problem lies in how to achieve the best performance when the camera processing capability and the network bandwidth are limited. In this paper, we propose a novel free viewpoint switching scheme for multi-view video scenario, in which the distributed video coding technique is employed. In t...

INTRODUCTION New Zealand's Pharmaceutical Management Agency (PHARMAC) manages the list of medicines available for prescribing with government subsidy, within a fixed annual medicines budget. PHARMAC achieves this through a mix of pricing strategies including reference pricing. In 2011, PHARMAC applied generic reference pricing to olanzapine tablets. AIM This study sought to evaluate change in...

Optical circuits are capable of providing large bandwidth improvements relative to electrical-switched networks in high-performance computing (HPC) systems. However, due to the circuit switching nature of optical systems, setup delays may prevent HPC systems from fully utilizing the available bandwidth. This paper proposes an applicationguided circuit management technique that can achieve laten...

Reaching-law-based discrete sliding mode controllers are well known to be easy tune and robust with respect disturbance. In recent years, it has been demonstrated that their robustness can further enhanced the use of arbitrary relative degree variables. However, reaching laws using such variables only ensure a good performance system when perturbations affecting plant matched, which is very res...
