This paper presents a new mechanism for data transmission over mobile networks. The ultimate goal of designing the next generation mobile network is to have a single network that can support all applications with different data attributes. The proposed mechanism in this paper is inspired by the Mechanism Design Theory that is an emerging branch of game theory and has been used successfully in economics...
This paper presents the application of switchable inductive tuning technique to the frequency tuning range (FTR) enhancement for millimeter-wave oscillators. By rearranging the induced-current path in the guard ring of a planar inductor, the inductance value can be changed and therefore the resulted total tuning range of the oscillator can be extended. Two VCOs are fabricated for demonstrating the...
In this paper, a new switched-mode bidirectional bridgeless AC/DC converter, operating in the discontinuous conduction mode (DCM), for automotive energy harvesting is presented. The simple topology consisting of common source n-MOSFETs allows for direct AC/DC conversion, minimum auxiliary circuits and simple gating patterns, when compared to other AC/DC converters proposed in the literatures. The...
This paper proposes a mechatronic suspension system with capabilities of energy regeneration and sky- hook (SK) control incorporated into the mechanism. The system overcomes the tradeoffs between energy consumption and ride comfort in an active suspension system. Central to the concept is development of a coupled switched-mode rectifier (SMR) capable of providing either a positive or negative damping...
This paper proposed a novel and simple sinusoidal boost-flyback continuous conduction mode (CCM) converter. This converter continuously produces half-sinusoidal voltage to a line frequency DC-AC inverter. This simple boost-flyback structure utilizes a coupled inductor to achieve a wider voltage gain range. The leakage inductance energy of the coupled inductor can be recycled to reduce the voltage...
An inductor switching DC/DC boost regulator with adaptive off/on time (AOOT) control is proposed in this paper. This system works with adaptive-off-time control in CCM while adaptive-on-time control in DCM. The burden caused by the switching frequency variation is reduced due to the quasi-fixed frequency switching by adaptive-off-time modulation under heavy-load condition. In DCM, adaptive-on-time...
A switching regulator with quasi-V2 adaptive on-time (AOT) control, that provides a fast load transient response is proposed. A feed-forward path network allows the proposed switching regulator to achieve a fast transient response and stable operation without requiring an output capacitor with a large equivalent series resistance. The proposed AOT controller makes the switching frequency pseudo fixed...
This paper have had quantitative analysis of the storage capacitance in EPC for phase stability of pulse TWTA. A new EPC scheme with low voltage storage capacity in input circuit is given. This scheme can reduce volume, mass, cost of the EPC and can improve TWTA reliability. Design and test results of EPC in the new scheme are proved.
This paper presents a bi-directional power flow interior permanent magnet brushless DC (IPM-BLDC) motor drive for electrical scooters. A new control scheme is proposed for the motoring operation. It has high energy conversion efficiency in the low speed and high torque region as well as high speed region. The basic control idea follows the maximum torque per ampere (MTPA) control of an interior permanent...
Packet classification problem has received much attention and continued to be an important topic in recent years. In packet classification problem, each incoming packet should be classified into flows according to a set of pre-defined rules. Grid-of-tries (GoT) is one of the traditional algorithmic schemes for solving 2-dimensional packet classification problem. The advantage of GoT is that it uses...
Network-on-chip (NoC) has been proposed as a solution for the global communication challenges of system-on-chip (SoC) design in the nanoscale technologies. In this paper, a methodology is presented to develop an efficient routing algorithm for network-on-chip platforms that are specialized for an application or a set of concurrent applications. The proposed routing methodology, based on the hybrid...
