Linearity Distortion Analysis of Junctionless Quadruple Gate MOSFETs for Analog Applications

Abstract: This paper examines a Junctionless quadruple gate (JLQG) MOSFET for analog and linearity distortion performance by numerically calculating transconductance and its higher order derivatives (gm1, gm2and gm3), VIP2, VIP3, IIP3 and IMD3. Influence of various physical device parameters: channel length, height (or width), gate oxide thickness, and channel doping concentration on the linearity distortion parameters are analyzed. From the numerical calculations it has been shown that the desirable characteristics for analog application at a given technology node are obtained for higher values of tSi, tox, and Nd. The present analysis also reveals the guidelines for the design of JLQG MOSFETs with least linearity distortion.

IP Paging for Mobile Hosts in Distributed and Fixed Hierarchical Mobile IP

Abstract: The concept of Paging has been found useful in existing cellular networks for mobile users with low call-to-mobility ratio CMR. It is necessary for fast mobility users to minimize the signaling burden on the network. Reduced signaling, also, conserves scarce wireless resources and provides power savings at user terminals. However, Mobile IP MIP, a base protocol for IP mobility, does not support paging concept in its original form. Several paging schemes and micro-mobility protocols, centralized and distributed, have been proposed in literature to alleviate the inherent limitations of Mobile IP. In this paper, the authors propose three paging schemes for Distributed and Fixed Hierarchical Mobile IP DFHMIP and develop analytical models for them. Performance evaluations of these schemes have been carried out and results have been compared with DFHMIP without paging and with Dynamic Hierarchical Mobile IP DHMIP for low CMR values.

Comparative study of advanced signal processing techniques for islanding detection in a hybrid distributed generation system

Abstract: In this paper, islanding detection in a hybrid distributed generation (DG) system is analyzed by the use of hyperbolic S-transform, time-time transform and mathematical morphology methods. The merits of these methods are thoroughly compared against commonly adopted wavelet transform and S-transform techniques, as a new contribution to earlier studies. The hybrid DG system consists of photovoltaic and wind energy systems connected to the grid within the IEEE 30-bus system. Negative sequence component of the voltage signal is extracted at the point of common coupling and passed through the above mentioned techniques. The efficacy of the proposed methods is also compared by energy based technique with proper threshold selection to accurately detect the islanding phenomena. Further, to augment the accuracy of the result, the classification is done using support vector machine to distinguish islanding from other power quality disturbances. The results demonstrate effective performance and feasibility of the proposed techniques for islanding detection under both noise-free and noisy environments, and also in the presence of harmonics.
