    • A closed-loop capacitance-to-frequency converter for single-element and differential capacitive sensors 

      Areekath, Lakshmi; George, Boby; Reverter Cubarsí, Ferran (2020-11-01)
      Article
      Accés obert
      A novel closed-loop switched-capacitor(SC) capacitance-to-frequency converter (CFC) is presentedin this paper. The proposed CFC is capable of measuring from either a single-element or a differential capacitive sensor, ...

    • A contactless capacitive angular-position sensor 

      Gasulla Forner, Manuel; Li, Xiujun; Meijer, Gerard C. M.; Van der Ham, Lucas; Spronck, Jo W. (Institute of Electrical and Electronics Engineers, 2003-10)
      Article
      Accés obert
      This paper presents an absolute capacitive angular-position sensor with a contactless rotor. The sensor is mainly composed of three parts: the capacitive sensing element, a signal processor, and a microcontroller. The ...

    • A high-speed capacitive-sensor interface using a relaxation oscillator and a fast counter 

      Gasulla Forner, Manuel; Li, Xiujun; Meijer, Gerard C. M. (Institute of Electrical and Electronics Engineers, 2003-05)
      Text en actes de congrés
      Accés obert
      This paper presents the analysis and experimental results on the jitter of a capacitive-sensor interface. The interface is implemented with a simple relaxation oscillator, a fast counter and a microcontroller. The goal ...

    • A novel low-cost smart leaf wetness sensor 

      Hornero Ocaña, Gemma; Gaitán Pitre, Jorge Eliécer; Serrano Finetti, Roberto Ernesto; Casas Piedrafita, Óscar; Pallàs-Areny, Ramon (2017-12-01)

    • An auto-balancing capacitance-to-pulse-width converter for capacitive sensors 

      Areekath, Lakshmi; George, Boby; Reverter Cubarsí, Ferran (2021-01)
      Article
      Accés obert
      A novel auto-balancing capacitance-to-pulse- width converter (CPC) that uses sinusoidal excitation, and operates in a closed-loop configuration, is presented in this paper. Unlike most of the existing CPCs, the ...

    • Direct interface for capacitive sensors based on the charge transfer method 

      Gaitán Pitre, Jorge Eliécer; Gasulla Forner, Manuel; Pallàs-Areny, Ramon (2007-05-01)
      Text en actes de congrés
      Accés obert
      We present the theoretical analysis and experimental performance results of a direct interface for capacitive sensors based on the charge transfer method when parasitic capacitances are included. The interface circuit ...

    • High-linearity front-end circuit for remote grounded capacitive sensors 

      Haberman, Marcelo A.; Spinelli, Enrique Mario; Reverter Cubarsí, Ferran (2021-02)
      Article
      Accés obert
      This paper presents a novel front-end circuit for remote grounded capacitive sensors. The circuit is insensitive to amplifier input capacitance and stray interconnecting-cable capacitances. It does not rely on neutralization ...
