• Verification system based on long-range iris and Graph Siamese Neural Networks 

      Zola, Francesco; Fernandez-Carrasco, José Álvaro; Bruse, Jan Lukas; Galar Idoate, Mikel Upna Orcid; Geradts, Zeno (ACM, 2022)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Biometric systems represent valid solutions in tasks like user authentication and verification, since they are able to analyze physical and behavioural features with high precision. However, especially when physical ...
    • WDM and TDM interrogation by sequentially pulsing direct modulated DFBs 

      Pérez-González, A.; Bravo Acha, Mikel Upna Orcid; Leandro González, Daniel Upna Orcid; Pérez Herrera, Rosa Ana Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (Optica, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A new versatile and cost-effective interrogation system by pulsing direct modulated (DM) DFB laser diodes is proposed. 1 pm wavelength resolution and 600 m sensor spacing is demonstrated by sequentially pulsing a DM DFB.
    • Wide-swing class AB regulated cascode current mirror 

      Garde Luque, María Pilar Upna Orcid; López Martín, Antonio Upna Orcid; Cruz Blas, Carlos Aristóteles de la Upna Orcid; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A micropower regulated cascode CMOS current mirror is presented, combining floating gate and quasi floating gate MOS transistors to achieve both wide swing and class AB operation, respectively. Measurement results for a ...
    • Worst expected ramp rates from cloud speed measurements 

      Wang, Guang Chao; Bosch, Juan Luis; Kurtz, Ben; Parra Laita, Íñigo de la Upna Orcid; Wu, Elynn (IEEE, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Large PV power ramp rates are of concern and sometimes even explicitly restricted by grid operators. Battery energy storage systems can smooth the power output and maintain ramp rates within permissible limits. To enable ...
    • Zero-loss switching in DC-DC series resonant converters under discontinuous conduction mode 

      Elizondo Martínez, David Upna Orcid; Barrios Rípodas, Ernesto Upna Orcid; Sanchis Gúrpide, Pablo Upna Orcid (IEEE, 2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Many thriving applications where isolation is required, such as traction and EV fast charging, implement solid-state transformers (SST). Half-cycle discontinuous-conduction-mode series resonant converters (HC-DCM-SRC) are ...
