Measuring the tolerance of self-adaptive clocks to supply voltage noise
Pérez Puigdemont, Jordi; Moll Echeto, Francisco de Borja; Cortadella, Jordi (2011)
Text en actes de congrés
Accés obertSimultaneous switching noise has become an important issue due to its signal integrity and timing implications. Therefore a lot of time and resources are spent during the PDN design to minimize the supply voltage variation. ... -
Optical nanoantenna optimization for local field enhancement at visible wavelengths
Pérez Puigdemont, Jordi (Universitat Politècnica de Catalunya, 2009-07-20)
Projecte Final de Màster Oficial
Accés obertDipole nanoantennas are studied by means of numerical calculations, over a broad frequency range (250-600 THz), in order to evaluate the benefits of its integration in NSOM microscopy systems. Operational wavelength, ... -
Single-walled carbon nanotubes characterization by Electron Spin Resonance spectroscopy
Abiad Monge, Aida; Pérez Puigdemont, Jordi; Ferrer Anglada, Núria; Roth, Segmar (2010)
Text en actes de congrés
Accés restringit per acord de confidencialitatCarbon nanotubes (CNTs) are interesting candidates for the development of new electronic devices and sensors due to their small size and their mechanical, optical and electrical properties [1-6]. Well-characterized ... -
Variation tolerant self-adaptive clock generation architecture based on a ring oscillator
Pérez Puigdemont, Jordi; Calomarde Palomino, Antonio; Moll Echeto, Francisco de Borja (Institute of Electrical and Electronics Engineers (IEEE), 2012)
Comunicació de congrés
Accés obertIn this work we propose a self-adaptive clock based on a ring oscillator as the solution for the increasing uncertainty in the critical path delay. This increase in uncertainty forces to add more safety margins to the ...
