A Power Efficient Gain Enhancing Technique for Current Mirror

This work introduces a new and simple method for adjusting the gain of current mirror. The major advantage of the proposed architecture is that, unlike the conventional variable gain current mirror, it does not need the change of the biasing current to adjust current gain. Therefore, the power dissipation remains constant in all of the gain settings. In addition, the proposed variable gain curr...

An interferometric technique for B/A measurement.

An isentropic phase method is described for measuring in vitro the acoustic nonlinearity parameter B/A of several aqueous buffers, protein solutions, lipid oils, and emulsions. The technique relies upon the use of an acoustic interferometer to measure the small changes in sound speed that accompany a rapid hydrostatic pressure change of between one and two atmospheres. Average accuracies of 0.8...

A Numerical Investigation of the Time Reversal Mirror Technique for Trans-skull Brain Cancer Ultrasound Surgery

Introduction: The medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. However, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. In this work, a model for 2D simulation of the time reversal mirror technique is proposed to study the possibil...

ScanSAR interferometric monitoring using the PS technique

A technique to provide quite accurate monitoring of small displacements by means of ASAR ScanSAR acquisition is here presented. This technique merges the advantages provided by Permanent Scatterers, namely the high accuracy, and the correlation over wide temporal and spatial baselines, with the advantages provided by WSM, in terms of short revisiting time and global coverage. It is then possibl...

A Technique for Interferometric Synthetic Aperture Sonar Image Processing

Interferometric Synthetic Aperture Sonar provides a means of obtaining high resolution three-dimensional images of objects on the sea floor. This paper describes a technique for forming images using interferometric sonar data. The technique is novel in the way it combines image co-registration and height estimation. Results of applying the technique to real sonar data are given.
