Inductive noise characterization and mitigation techniques for modern computer systems
… the challenges of processor power delivery and voltage noise become increasingly difficult to address. This thesis characterizes voltage emergencies and evaluates voltage noise mitigation techniques across a range of processors and power distribution networks. Each processor class has unique …

Spin Shot Noise measurement
Charge shot noise, the intrinsic fluctuations in the electrical current resulting from the statistics of the arrival of discrete electronic charges, was predicted more than a century ago2 and has been an invaluable tool for examining the mechanism of charge transport and the nature of …

Percolation and nanosecond fluctuators in V2O3 films within the metal-insulator transition
… range of phase coexistence. Resistive noise measured through electronic transport is a probe of percolation and the fluctuating dynamics of the two-phase domain structure. We measure voltage noise spectra at both low frequencies (up to 100 kHz) and radio frequencies (between 10 MHz and …

Fluctuations in dc SQUIDs: Quantum Noise Effects, Low Frequency Noise, and Single Electron Trapping
We have studied the signal and noise properties of extremely sensitive dc SQUIDs composed of submicron area tunnel junctions. At high frequencies, the flux resolution is expected to be limited by intrinsic quantum fluctuations, making these devices prime candidates for ideal quantum-limited …

Two-ion control and polarization forces for precise mass comparisons
… ions was completely limited by magnetic field noise. Our new technique reduces the impact of both magnetic field and trap voltage noise by more than three orders of magnitude. We can measure and control the relative motion of the two ions in the Penning trap. We have developed a new mode …

Driven Magnetic Flux Lines in Type-II Superconductors: Nonequilibrium Steady States and Relaxation Properties
… system by means of the force-velocity / current-voltage curve, static structure factor, mean vortex radius of gyration, number of double-kink and half-loop excitations, and velocity / voltage noise features. We compare the results for the above quantities for randomly distributed point and …

Correlation lengths, disorder, and dynamics of vortex matter as heard through the noise
… a series of experiments measuring flux-flow voltage noise in the type II superconductor 2H-NbSe₂ concentrating on the dynamics and possible phase transitions of vortex matter associated with the peak-effect. I emphasize five conclusions: (1) Traditional models of vortex dynamics relying on …

A Study of Narrowband Noise Characteristics Associated with Vortex Motion in High Temperature Superconductors
… differently. To investigate their motion, voltage noise generated by moving vortices is studied for different material defect types using a nonequilibrium Metropolis Monte Carlo simulation. The current-voltage (I-V) characteristics obtained from the simulation for various vortex densities …

Phase dynamics and magnetic field response of proximity-coupled superconductor arrays
… Above Te the free vortices give rise to a d.c. voltage --and therefore resistance --in the presence of a current bias. The theoretical picture is less clear in the presence of. a magnetic field, where a background lattice of vortices adds frustration and the possibility of additional types of …

Effect of noise on the pull-in dynamics of an electrostatic microswitch
… this research is to investigate the effects of noise on the pull-in dynamics of a micro-electromechanical switch. We take into account thermal noise and noise present in the voltage source. Thermal noise is modeled as white noise. First, we study its effect on the linear response of the system. …
