    • Accelerating hydrogen sensing with Pd-Mos capacitors using active controls of trapped charge 

      Solà Peñafiel, Nil; López Rodríguez, Gema; Sindreu Cladera, Pau; Navarrete Gatell, Eric; Llobet, Eduard; Ramos Castro, Juan José; Martín García, Isidro; Manyosa i Vilardell, Xavier; Bermejo Broto, Sandra; Domínguez Pumar, Manuel (Elsevier, 2024-11)
      Article
      Open Access
      Hydrogen monitoring with reliable, fast and cheap sensors is crucial to fully exploit the potential of this gas as an energy vector. One of the most appealing technologies for hydrogen sensing is based on MOS capacitors ...

    • Acceleration and drift reduction of MOX gas sensors using active sigma-delta controls based on dielectric excitation 

      Solà Peñafiel, Nil; Manyosa i Vilardell, Xavier; Navarrete Gatell, Eric; Ramos Castro, Juan José; Jiménez Serres, Vicente; Bermejo Broto, Sandra; García, Isabel; Llobet Valero, Eduard; Domínguez Pumar, Manuel (2022-08-15)
      Article
      Open Access
      The objective of this paper is to apply a closed-loop control based on dielectric excitation to MOX gas sensors in order to improve their response time. The control implements a feedback loop in which temperature modulations ...

    • Understanding noise-shaping in sigma-delta controls of surface potential for MOX gas sensors 

      Domínguez Pumar, Manuel; Kowalski, Lukasz; Monge Villora, Oscar; Olm Miras, Josep Maria; Navarrete Gatell, Eric; Llobet Valero, Eduard; Pons Nin, Joan (Institute of Electronics, Information and Communications Engineers (IEICE), 2018)
