    • A Closed-loop capacitance to pulse-width converter for single element capacitive sensors 

      Areekath, Lakshmi; George, Boby; Reverter Cubarsí, Ferran (2019)
      Conference report
      Open Access
      A novel closed-loop capacitance-to-pulse width converter (CPC) suitable for single element capacitive sensors that use sinusoidal excitation is presented in this paper. Its operation is realized using a new configuration ...

      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 Simple direct microcontroller interface for capacitively-coupled resistive sensors 

      Areekath, Lakshmi; George, Boby; Reverter Cubarsí, Ferran (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Restricted access - publisher's policy
      A novel approach to interface capacitively-coupled resistive sensors directly to a microcontroller is presented in this paper. The existing schemes for the measurement of the resistance of a sensing element ...
    • An Extended study on an interference-insensitive switched capacitor CDC 

      Areekath, Lakshmi; Reverter Cubarsí, Ferran; George, Boby (2019-09-15)
      Article
      Restricted access - publisher's policy
      A new Switched Capacitor (SC) Capacitance-to-Digital Converter (CDC) is presented in this paper. Its output exhibits a high-level of insensitivity to interference, by virtue of the conversion mechanism itself. The proposed ...
