Abstract
An electronic device for determining a status of a touch sensor includes a capacitance measurement circuit to be coupled to a touch sensor including first and second electrodes, the capacitance measurement circuit being configured to obtain a first measurement result based on a self-capacitance of the first electrode and a second measurement result based on a mutual capacitance between the first and the second electrodes. An algorithm may be applied to the first and second measurement results, thereby generating a signal. A threshold comparator is configured to compare the signal to a threshold, and to generate a comparison signal having a first value if the signal is greater than the threshold and a second value if the signal is less than the threshold. An output module is configured to provide an output signal indicative of the status of the touch sensor based on the comparison signal.
