Design and Analysis of a 90 nm mm-Wave Oscillator Using Inductive-Division LC Tank
TL;DR: The proposed inductive division reduces the phase noise by increasing the signal amplitude across the varactor, without affecting the operation mode of the cross-coupled pair transistors, and helps to increase the tuning range by isolating thevaractor from the parasitic capacitances of the transistors and interconnects.

Environmental sensitivities of quartz oscillators
Fred L. Walls,J.-J. Gagnepain +1 more
TL;DR: The physical basis for the sensitivity of precision oscillators to temperature, humidity, pressure, acceleration and vibration, magnetic field, electric field, load, and radiation is examined.
Journal ArticleDOI
A digitally controlled oscillator system for SAW-less transmitters in cellular handsets
TL;DR: The measured phase noise of -167 dBc/Hz at 20 MHz offset from 915 MHz carrier and frequency tuning range of 24.5% proves that this DCO system can be used in SAW-less quad-band transmitters for mobile phones.
Journal ArticleDOI
Design of a 24-GHz CMOS VCO With an Asymmetric-Width Transformer
TL;DR: It is shown that the inductance ratio of the transformer must be optimized, and asymmetric-width transformers allow the easy optimization and the high Q-factor of the VCO.
Journal ArticleDOI
A BiCMOS W-Band 2×2 Focal-Plane Array With On-Chip Antenna
TL;DR: This work demonstrates the highest integration level of any silicon-based systems in the 94 GHz imaging band in a standard 0.18 μm SiGe BiCMOS process.

Short-term frequency stability: Characterization, theory, and measurement
TL;DR: In this article, an analysis is presented of the manner in which oscillator short-term instabilities limit performance in a number of applications, and the authors provide guidelines for theoretical formulations, the definition of "short-term stability" and the development of measurement techniques for characterizing short-time instabilities.
