      A novel fully differential (FD) demodulator is presented. Using different design strategies, the circuit can be used for processing amplitude-modulated (AM) signals obtained from impedance measurements or coming from ...
    • Measuring dynamic signals with direct sensor-to-microcontroller interfaces applied to a magnetoresistive sensor 

      Sifuentes, Ernesto; González Landaeta, Rafael; Cota Ruiz, Juan; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2017-05-18)
      Article
      Open Access
      This paper evaluates the performance of direct interface circuits (DIC), where the sensor is directly connected to a microcontroller, when a resistive sensor subjected to dynamic changes is measured. The theoretical analysis ...
    • Microcontroller-Based Seat Occupancy Detection and Classification 

      Sifuentes, Ernesto; González Landaeta, Rafael; Cota Ruiz, Juan; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2018)
      Conference lecture
      Open Access
      This paper presents a microcontroller-based measurement system to detect and confirm the presence of a subject in a chair. The system relies on a single Force Sensing Resistor (FSR), which may be arranged in the seat or ...
