Characterization of wireless propagation in complex indoor environments
Azpilicueta Fernández de las Heras, Leyre
(2015)
Tesis doctoral / Doktoretza tesia 
En este trabajo de investigación se ha propuesto un nuevo modelo de propagación determinista para analizar la propagación radioeléctrica en entornos complejos. En primer lugar, se ha realizado un profundo análisis de los ... -
Design of low-cost smart accelerometers
Carlosena García, Alfonso ; López Martín, Antonio ; Massarotto, Marco ; Cruz Blas, Carlos Aristóteles de la ; Lecumberri Villamediana, Pablo ; Gómez Fernández, Marisol ; Pintor Borobia, Jesús María ; Gárriz Sanz, Sergio (Universitat Politècnica de Catalunya, 2005)
Contribución a congreso / Biltzarrerako ekarpena
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric element as basic sensing material, and adding a mixed-mode conditioning circuit. -
Design of MOS-translinear multiplier/dividers in analog VLSI
López Martín, Antonio ; Carlosena García, Alfonso (Hindawi Publishing Corporation, 2000)
Artículo / Artikulua
A general framework for designing current-mode CMOS analog multiplier/divider circuits based on the cascade connection of a geometric-mean circuit and a squarer/ divider is presented. It is shown how both building blocks ... -

Low-power class-AB CMOS voltage feedback current operational amplifier with tunable gain and bandwidth
Esparza Alfaro, Fermín; Pennisi, Salvatore; Palumbo, Gaetano; López Martín, Antonio (IEEE, 2014)
Artículo / Artikulua
A CMOS class AB variable gain Voltage Feedback Current Operational Amplifier (VFCOA) is presented. The implementation is based on class AB second generation current conveyors and exploits an electronically tunable ... -
A novel PLL architecture
Osa, Juan I.; Carlosena García, Alfonso ; López Martín, Antonio (2000)
Contribución a congreso / Biltzarrerako ekarpena
A novel phase-locked loop scheme is proposed in this paper, whose main distinguishing features are infinite hold-in range, pull-out range fractionally constant and also a ripple fractionally constant. To this end, it ... -
Power-efficient current-mode analog circuits for highly integrated ultra low power wireless transceivers
Esparza Alfaro, Fermín (2014)
Tesis doctoral / Doktoretza tesia
In this thesis, current-mode low-voltage and low-power techniques have been applied to implement novel analog circuits for zero-IF receiver backend design, focusing on amplification, filtering and detection stages. The ... -
