    • Folded Cascode OTA with 5540 MHzpF/mA FoM 

      Garde Luque, María Pilar; López Martín, Antonio Upna; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced ...
    • On the optimal current followers for wide-swing current-efficient amplifiers 

      López Martín, Antonio Upna; Garde Luque, María Pilar; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to ...
    • Optical fiber networks for remote fiber optic sensors 

      Fernández Vallejo, Montserrat Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2012)   Artículo / Artikulua  OpenAccess
      This paper presents an overview of optical fiber sensor networks for remote sensing. Firstly, the state of the art of remote fiber sensor systems has been considered. We have summarized the great evolution of these systems ...
    • Super class AB RFC OTA with adaptive local common-mode feedback 

      Garde Luque, María Pilar; López Martín, Antonio Upna; Carvajal, R.G.; Ramírez-Angulo, J. (Institution of Engineering and Technology, 2018)   Artículo / Artikulua  OpenAccess
      A super class AB recycling folded cascode operational transconductance amplifier is presented. It employs local common-mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different ...
