TIMEPIECE OSCILLATOR

Simon Nessim Henein

The invention relates to a rotating oscillator for a timepiece comprising a support element designed to allow the oscillator to be assembled on a timepiece, a balance, a plurality of flexible blades connecting the support element to the balance and able to ...

Clocks do not tick in unison: isolation of Clock and vrille shed new light on the clockwork model of the sand fly Lutzomyia longipalpis

Antonio Carlos Alves Meireles Filho

Background: Behavior rhythms of insect vectors directly interfere with the dynamics of pathogen transmission to humans. The sand fly Lutzomyia longipalpis is the main vector of visceral leishmaniasis in America and concentrates its activity around dusk. De ...

Signaling in 3-D integrated circuits, benefits and challenges

Somayyeh Rahimian Omam

Three-dimensional (3-D) or vertical integration is a design and packaging paradigm that can mitigate many of the increasing challenges related to the design of modern integrated systems. 3-D circuits have recently been at the spotlight, since these circuit ...

The Microloop-Gap Resonator: A Novel Miniaturized Microwave Cavity for Double-Resonance Rubidium Atomic Clocks

Anja Skrivervik, Francesco Merli, Maddalena Violetti

Nowadays mobile and battery-powered applications push the need for radically miniaturized and low-power frequency standards that surpass the stability achievable with quartz oscillators. For the miniaturization of double-resonance rubidium (Rb-87) atomic c ...

Method for estimating and correcting a drift between clocks of receiving transceiver and a corresponding emitting transceiver, and receive for implementing said method

Jean-Yves Le Boudec, Ruben Merz

Method for estimating and correcting a frequency offset between a local clock of a receiving transceiver and a remote clock of an emitting transceiver comprises receiving by said receiving transceiver, a signal emitted by the emitting transceiver, said sig ...

A Self-Regulating Oscillator for Sensor Operation of Nanoelectromechanical Systems

Maher Kayal, Marc Pastre, Christian Kauth

A closed-loop oscillator topology is proposed for dynamic sensor operation of nanoelectromechanical systems, benefiting from the structure's quality factor. Automatic adaptation to diverse sensors' properties is achieved via a self-regulating phase-locked ...

An Enhanced Design Methodology for Resonant Clock Trees

Giovanni De Micheli, Vasileios Pavlidis, Xifan Tang, Somayyeh Rahimian Omam

Clock distribution networks consume a considerable portion of the power dissipated by synchronous circuits. In conventional clock distribution networks, clock buffers are inserted to retain signal integrity along the long interconnects, which, in turn, sig ...

Optically-Clocked Instruction Set Extensions for High Efficiency Embedded Processors

Edoardo Charbon, Claudio Favi, Ties Jan Henderikus Kluter, Christian Mester

We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical s ...

A Low-Overhead Method for Pre-bond Test of Resonant 3-D Clock Distribution Networks

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low power alternatives to con- ventional ...
