    • A cmos-mems beol 2-axis lorentz-force magnetometer with device-level offset cancellation 

      Sánchez Chiva, José María; Valle Fraga, Juan José; Fernández, Daniel; Madrenas Boadas, Jordi (2020-10-19)
      Article
      Open Access
      Lorentz-force Microelectromechanical Systems (MEMS) magnetometers have been proposed as a replacement for magnetometers currently used in consumer electronics market. Being MEMS devices, they can be manufactured in the ...
    • A mixed-signal control system for Lorentz-force resonant MEMS magnetometers 

      Sánchez Chiva, José María; Valle Fraga, Juan José; Fernández, Daniel; Madrenas Boadas, Jordi (2019-09-01)
      Article
      Open Access
      This paper presents a mixed-signal closed-loop control system for Lorentz force resonant MEMS magnetometers. The control system contributes to 1) the automatic phase control of the loop, that allows start-up and keeps ...

      Master thesis (pre-Bologna period)
      Open Access
      Aquest projecte és una recerca dels mètodes existents per a la transferència d’energia sense contacte elèctric, seguida d’una investigació de les característiques de cada mètode i un estudi de la viabilitat de cadascun ...
    • Under pressure? Don’t lose direction! Smart sensors: Development of CMOS and MEMS on the same platform 

      Sánchez Chiva, José María; Banerji, Saoni (2016)
      Conference lecture
      Open Access
      Micro Electro Mechanical Systems (MEMS) are movable structures fabricated on the surface of silicon chips by selectively depositing and etching away materials and silicon. Such movement allows the measurement of a wide ...
