Self-controlled 4-transistor low-power min-max current selector
(2009-10)
Article
Restricted access - publisher's policyFour cross-coupled MOS transistors operating as switches implement a very compact, fast, low-power and precise minimum and maximum current selector. Local positive feedback allows the circuit to work without the need of ... -
Closed-form equation for natural frequencies of beams under full range of axial loads modeled with a spring-mass system
(2019-04-01)
Article
Open AccessA new simple closed-form equation that accurately predicts the effect of an arbitrarily large constant axial load, residual stress or temperature shift on the natural frequencies of an uniform single-span beam, with various ... -
On the ability of adaptation of speech signals and data hiding
(2012-11-15)
Article
Restricted access - publisher's policyThe efficient wavelet masking is a scheme of speech-in-speech hiding based on the ability of adaptation of speech signals under the hypothesis “any (speech) secret signal may seem similar to a (speech) host signal if its ... -
SNAVA—A real-time multi-FPGA multi-model spiking neural network simulation architecture
(2018-01-01)
Article
Open AccessSpiking Neural Networks (SNN) for Versatile Applications (SNAVA) simulation platform is a scalable and programmable parallel architecture that supports real-time, large-scale, multi-model SNN computation. This parallel ... -
Curvature of BEOL cantilevers in CMOS-MEMS processes
(2017-08-01)
Article
Open AccessThis paper presents the curvature characterization results of released back-end-of-line 5 µm-wide cantilevers for two different 0.18-µm 1P6M complementary metal-oxide semiconductor microelectromechanical systems processes. ... -
CMOS-MEMS resonant pressure sensors: optimization and validation through comparative analysis
(2017-09-01)
Article
Open AccessAn optimized CMOS-MEMS resonant pressure sensor with enhanced sensitivity at atmospheric pressure has been reported in this paper. The presented work reports modeling and characterization of a resonant pressure sensor, ... -
Characterization of CMOS-MEMS resonant pressure sensors
(2017-08-30)
Article
Open AccessIEEE Comprehensive characterization results of a CMOS-MEMS resonant pressure sensor are presented. We have extensively evaluated the key performance parameters of our device in terms of quality factor (Q) variations under ... -

Modified current-mode one-cycle control for linear–assisted DC/DC regulator
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference lecture
Restricted access - publisher's policyLinear-assisted DC/DC converters are structures that allow to take advantages of the two classic alternatives in the design of power supply systems: Voltage linear regulators (classic NPN topology or LDO –low dropout–) and ... -
Speech scrambling based on imitation of a target speech signal with non-confidential content
(2014-05-15)
Article
Restricted access - publisher's policyThis paper shows a new approach of speech scrambling using imitation to produce a scrambled speech signal with intelligible content. The secret message imitates a target speech signal with non-confidential content through ... -
Quasi-digital front-ends for current measurement in integrated circuits with giant magnetoresistance technology
(2014-07-01)
Article
Restricted access - publisher's policyIn this study, the authors report on two different electronic interfaces for low-power integrated circuits electric current monitoring through current-to-frequency (I-f) conversion schemes. This proposal displays the ... -
Design of an on–chip linear–assisted DC–DC voltage regulator
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference lecture
Restricted access - publisher's policyThis article shows the design of an on-chip CMOS linear-assisted DC-DC regulator. It results a good alternative topology to classic switching DC-DC power converters. In the presented technique, an auxiliary linear regulator ...
