    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
    Open Access
    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)
    Conference report
    Open Access
    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 ...
  • The noise performance of a high-speed capacitive-sensor interface based on a relaxation oscillator and a fast counter 

    Gasulla Forner, Manuel; Li, Xiujun; Meijer, Gerard C. M. (Institute of Electrical and Electronics Engineers, 2005-10)
    Article
    Open Access
    This paper presents the analysis and experimental results on the noise performances of a capacitive-sensor interface. The interface is able to measure low capacitance values in the order of picofarads and is implemented ...
