    • A 1.2-V current-mode RMS-to-DC converter based on a novel two-quadrant electronically simulated MOS translinear loop 

      Martincorena Arraiza, Maite; Cruz Blas, Carlos Aristóteles de la Upna Orcid; Algueta-Miguel, Jose M. Upna Orcid; López Martín, Antonio Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      A novel current-mode CMOS RMS-to-DC converter using translinear techniques is introduced. It is based on a squarer/divider cell that is implemented using an electronically simulated loop with a novel biasing scheme that ...
    • A combination of a vibrational electromagnetic energy harvester and a giant magnetoimpedance (GMI) sensor 

      Beato López, Juan Jesús Upna Orcid; Royo, Isaac Upna Orcid; Algueta-Miguel, Jose M. Upna Orcid; Gómez Polo, Cristina Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric ...
    • Energy harvesting approaches in IoT scenarios with very low ambient energy 

      López Martín, Antonio Upna Orcid; Algueta-Miguel, Jose M. Upna Orcid; Matías Maestro, Ignacio Upna Orcid (European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The feasibility of multi-source energy harvesting in Internet of Things (IoT) scenarios with low and intermittent ambient energy is addressed. As a relevant case study, application to a smart cargo container system is ...
    • Low-power ultrasonic front-end for cargo container monitoring 

      Algueta-Miguel, Jose M. Upna Orcid; García Oya, José Ramón; López Martín, Antonio Upna Orcid; Cruz Blas, Carlos Aristóteles de la Upna Orcid; Muñoz Chavero, Fernando; Hidalgo Fort, Eduardo (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      A low-power ultrasonic communication system conceived for cargo container monitoring is presented. Two piezoelectric transducers operating at 40 kHz are used for generating and acquiring an ultrasonic signal through the ...
