Feasibility Study of Analogue and Digital Temperature Sensors in Nanoscale CMOS Technologies

The downscaling of CMOS technology gives rise to a myriad of nanoscale effects. At the same time, power density and thus heat generation increases. The aim of this paper is to evaluate the feasibility of both analogue and digital temperature sensors in nanoscale CMOS using the Berkeley Predictive Technology Model (BPTM) for 65nm. For the...

Coupling of a CMOS Optical Sensor to a Micromachined Deformable Mirror with an Adaline Neural Method

We report on the preliminary results of an Adaline neural method for the coupling of a custom CMOS wavefront sensor to a micromachined adaptive mirror. The algorithm does not rely on a fixed basis matrix -as opposed to traditional methods-, offers excellent immunity to round-off errors and admits real-time input adaptability to speed up...

Silicon micro-optics for smart light control

We present an overview of the results of our recent research in the field of adaptive optical components based on silicon microtechnologies, including membrane deformable mirrors, spatial light modulators, liquid-crystal correctors, wavefront sensors, and both spherical and aspherical micro-optical components. We aim at the realization of...

CMOS-based Integrated Wavefront Sensor

This thesis addresses the design, implementation and performance of an integrated Hartmann-Shack wavefront sensor suitable for real-time operation and compatible with a standard technology. A wavefront sensor can be used for the detection of distortions in the profile of a light beam or of an optical component.With such a sensor, one can, for...
