A novel high-throughput on-wafer electromechanical sensitivity characterization system for piezoresistive cantilevers
Luis Guillermo Villanueva Torrijo
In this work we present the development of a new set-up that allows on-wafer sensitivity characterization of piezoresistive cantilevers. In this way we reduce considerably the testing time compared to the techniques available up to date but at the same tim ...
2012High-Dimensional Bayesian Clustering with Variable Selection: The R Package bclus
Anthony Christopher Davison, Vahid Partovi Nia
The R package bclust is useful for clustering high-dimensional continuous data. The package uses a parametric spike-and-slab Bayesian model to downweight the effect of noise variables and to quantify the importance of each variable in agglomerative cluster ...
2012Optimal operating points of oscillators using nonlinear resonators
Luis Guillermo Villanueva Torrijo
We demonstrate an analytical method for calculating the phase sensitivity of a class of oscillators whose phase does not affect the time evolution of the other dynamic variables. We show that such oscillators possess the possibility for complete phase nois ...
2012Passive Phase Noise Cancellation Scheme
Luis Guillermo Villanueva Torrijo
We introduce a new method for reducing phase noise in oscillators, thereby improving their frequency precision. The noise reduction is realized by a passive device consisting of a pair of coupled nonlinear resonating elements that are driven parametrically ...
American Physical Society2012Clock Jitter Compensation in High-Rate ADC Circuits
Clock timing jitter refers to random perturbations in the sampling time in analog-to-digital converters (ADCs). The perturbations are caused by circuit imperfections in the sampling clock. This paper analyzes the effect of sampling clock jitter on the acqu ...
IEEE2012Nonquadratic Stochastic Model Predictive Control: A Tractable Approach
This paper deals with the nite horizon stochastic optimal control problem with the expectation of the p-norm as the objective function and jointly Gaussian, although not necessarily independent, additive disturbance process. We develop an approximation str ...
