Design and Implementation of highly efficient Reflective type phase shifters (RTPS) at 60GHz has been proposed in this work. Low loss cost effective design which utilizes less chip area is proposed. At high frequencies, to improve the efficiency of the communication system highly directional high gain antennas have to be used. Phase shifters are one of the most important elements in phased arra...

Efficient wireless energy transfer between two inductor-capacitor circuits has been demonstrated by applying the principles of Coupled Mode Theory to create a system of strongly-coupled, resonating magnetic fields. This paper makes a detailed analyzes how Coupled Mode Theory is used to increase energy transfer between two simple inductor-capacitor circuits.

A new 3-D solenoid-inductor structure that is compatible with standard CMOS technology is proposed. Simulation shows excellent area efficiency of more than 80% saving over conventional planar spiral inductor. If combined with post-micromaching, a peak quality factor greater than 10 at 30GHz can be realized.

Modeling and performance of on-chip spiral inductors is presented. Y-parameters are obtained from the measured S-parameters of the inductor fabricated in 0.35-μm SOI CMOS technology. Matlab is used to get the π-equivalent circuit model parameters at each frequency point. The SOI CMOS inductor shows better performance characteristics in terms of Q-factor and self-resonance frequency.

Easy to use multifunctional wearable devices, with no wires hanging around, are needed for real time health monitoring at user's comfort. Herein, an inductor-capacitor (LC) resonant tank-based wireless pressure sensor, screen-printed on electrospun Poly-L-lactide (PLLA) nanofibers-based flexible, biocompatible, and piezoelectric substrate is presented. The printed tank (resonant frequency of ≈1...

The voltage controlled oscillator (VCO) is one of the most important building blocks in modern communication applications such as microprocessor clock generation, wired and wireless communications, system synchronization, and frequency synthesis. The design of high performance VCOs has been increasingly more important and still is an active research area. Research on VCOs for the past decade ha...

This article presents a ground breaking traction drive for fuel cell-powered light rail vehicles based on multilevel cascade converter with H-bridge cells. The provides dc–ac power conversion unique buck–boost capability to compensate the variation of cell terminal voltage load power. In comparison conventional boost inverter, connection dc–dc and source proposed has significant benefits much s...

Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) was first isolated in swine alveolar macrophages (SAMs) and has subsequently been reported to replicate in other cell lines. Entry of the virus inside the cell takes place by receptor-mediated endocytosis. Following the entry of the virus into the cell, several not completely understood changes take place. PRRSV has been reported to be...
