  • Patent number: 9791488
    Abstract: A sensor for sensing a parameter includes a capacitor, a switch and a comparator. The capacitor is configured to be charged or discharged by at least one of a first current signal or a second current signal. The switch is configured to selectively connect or disconnect the first current signal and the capacitor in response to a feedback signal. The comparator is coupled with the capacitor and configured to output an output voltage based on a comparison of a capacitor voltage of the capacitor to a reference voltage. The first current signal is independent of the parameter, and the second current signal is dependent on the parameter. The output voltage defines the feedback signal and is indicative of a value of the parameter detected by the sensor.
