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.
Journal ArticleDOI
Millimeter-wave CMOS design
TL;DR: In this paper, the effects of parasitics on the high-frequency performance of 130-nm CMOS transistors are investigated, and a peak f/sub max/ of 135 GHz has been achieved with optimal device layout.
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.
Patent
Wireless physiological sensor patches and systems
TL;DR: In this article, the authors present methods, devices, and systems for wireless physiological sensor patches and systems which incorporate these patches using a structure where the processing is distributed asymmetrically on the two or more types of ASIC chips that are designed to work together.
Journal ArticleDOI
