Journal ArticleDOI
Analysis, design, and optimization of spiral inductors and transformers for Si RF ICs
Ali M. Niknejad,Robert G. Meyer +1 more
TL;DR: In this article, the authors used classic circuit analysis and network analysis techniques to derive two-port parameters from spiral inductors and transformers and applied them to traditional square and polygon inductors, as well as multilayer metal structures and coupled inductors.

Wireless non-radiative energy transfer
TL;DR: In this paper, the authors proposed an electromagnetic energy transfer device that includes a first resonator structure receiving energy from an external power supply, and a second resonance structure is positioned distal from the first, and supplies useful working power to an external load.
Journal ArticleDOI
An ultrawideband CMOS low-noise amplifier for 3.1-10.6-GHz wireless receivers
TL;DR: An ultrawideband 3.1-10.6-GHz low-noise amplifier employing an input three-section band-pass Chebyshev filter using a 0.18-/spl mu/m CMOS process achieves a power gain of 9.3 dB with an input match of -10 dB over the band.
Journal ArticleDOI
From RSSI to CSI: Indoor localization via channel response
Zheng Yang,Zimu Zhou,Yunhao Liu +2 more
TL;DR: In this article, the authors survey the channel state information (CSI) in 802.11 a/g/n and highlight the differences between CSI and RSSI with respect to network layering, time resolution, frequency resolution, stability, and accessibility.
Journal ArticleDOI
WiFall: Device-Free Fall Detection by Wireless Networks
TL;DR: This work analyzes the wireless signal propagation model considering human activities influence and proposes a novel and truly unobtrusive detection method based on the advanced wireless technologies, which it is called as WiFall, which withdraws the need for hardware modification, environmental setup and worn or taken devices.
