    • A novel sensor-bridge-to-microcontroller interface 

      Custodio Ruiz, Ángel; Bragós Bardia, Ramon; Pallàs Areny, Ramon (Institute of Electrical and Electronics Engineers, 2001-05)
      Conference report
      Open Access
      Sensor bridges are usually interfaced to microcontrollers by supplying the bridge with a voltage or current and digitizing the resulting voltage or current after being amplified and low-pass filtered. This paper proposes ...
    • Error analysis and reduction for a simple sensor-microcontroller interface 

      Custodio Ruiz, Ángel; Pallàs Areny, Ramon; Bragós Bardia, Ramon (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-12-31)
      Article
      Open Access
      Error analysis of a resistive sensor-to-microcontroller interface based on pulse-width modulation and time–ratio measurement shows that internal input and output resistances in microcontroller digital ports produce zero, ...
