All-digital self-adaptive PVTA variation aware clock generation system for DFS
(2014)
Conference report
Open AccessAn all-digital self-adaptive clock generation system capable of adapt the clock frequency to compensate the effects of PVTA variations on the IC propagation delay and satisfy an externally set propagation length condition ... -
All-digital simple clock synthesis through a glitch-free variable-length ring oscillator
(2014-02-01)
Article
Restricted access - publisher's policyThis brief presents a simple all-digital variable-length ring oscillator (VLRO) design that is capable of synchronously changing the output frequency while keeping a signal free of glitches or spurious oscillations at the ... -

Flexible, transparent electrodes using carbon nanotubes
(2012-12-10)
Article
Open AccessWe prepare thin single-walled carbon nanotube networks on a transparent and flexible substrate with different densities, using a very simple spray method. We measure the electric impedance at different frequencies Z(f) in ... -
High-frequency impedance of single-walled carbon nanotube networks on transparent flexible substrate
(2014-12-01)
Article
Restricted access - publisher's policyTransparent and flexible networks with randomly distributed single-walled carbon nanotubes (SWCNTs) are emerging as novel materials for various applications, particularly as electronic materials. We investigate the ... -

Measuring the tolerance of self-adaptive clocks to supply voltage noise
(2011)
Conference report
Open AccessSimultaneous 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
(Universitat Politècnica de Catalunya, 2009-07-20)
Master thesis
Open AccessDipole 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
(2010)
Conference report
Restricted access - confidentiality agreementCarbon 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
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference lecture
Open AccessIn 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 ...
