who gave me the opportunity to work in this group. I am particularly grateful for the assistance given by my patient supervisor Janko Katic. His guidance and suggestions were indispensable for the design of the presented circuits. The excellent plan gave me the proper passion to carry through this Master Thesis. I would thank Ayobami and Jiazuo for sharing with me the office and a portion of th...

Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

   Nowadays, one of the most important blocks in telecommunication circuits is the frequency synthesizer and the frequency multipliers. Phase-frequency detectors are the inseparable parts of these circuits. In this paper, it has been attempted to design two new structures for phase-frequency detectors in QCA nanotechnology. The proposed structures have the capability of detecting the phase ...

This paper targets the unexplored problem of demand response within the context of power-grids that are allowed to regularly enforce blackouts as a mean to balance supply with demand: highly-stressed grids. Currently these utilities use as a cyclic and binary (power/no-power) schedule over consumer groups leading to significant wastage of capacity and long hours of no-power. We present here a n...

Academic Year 2013. . To Paola, because no matter what it has always been the two of us.

low-power lasers are a group of lasers with a power less than 250 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. these lasers have analgesic features with their ability to trigger reactions that reduce pain and inflammatory mediators. low-power lasers can also be used instead of needles in acupuncture to dec...
