Linear time-invariant (LTI) phase noise theories provide important qualitative design insights
but are limited in their quantitative predictive power. Part of the difficulty is that device noise …

Based on a physical understanding of phase-noise mechanisms, a passive LC filter is found
to lower the phase-noise factor in a differential oscillator to its fundamental minimum. Three …

A harmonic oscillator topology displaying an improved phase noise performance is
introduced in this paper. Exploiting the advantages yielded by operating the core transistors …

Underlying physical mechanisms controlling the noise properties of oscillators are studied.
This treatment shows the importance of inductance selection for oscillator noise …

A strong demand for wireless products, an insatiable thirst for spectrum that pushes carrier
frequencies ever upward, and the constant quest for higher performance at lower power and …

Low-Frequency Noise in Advanced CMOS Devices begins with an introduction to noise,
describing the fundamental noise sources and basic circuit analysis. The characterization of …

The demand for radio frequency (RF) integrated circuits with reduced power consumption is
growing owing to the trend toward system-on-a-chip (SoC) implementations in deep-sub …

This paper presents two 1.8 GHz CMOS voltage-controlled oscillators (VCOs), tuned by an
inversion-mode MOS varactor and an accumulation-mode MOS varactor, respectively. Both …

This paper presents a fully wireless cardiac pressure sensing system. Food and Drug
Administration (FDA) approved medical stents are explored as radiating structures to …

A 1.8-GHz LC VCO designed in a 0.18-/spl mu/m CMOS process achieves a very wide
tuning range of 73% and measured phase noise of-123.5 dBc/Hz at a 600-kHz offset from a …
