Abstract
Embodiments relate to an apparatus for determining a sensitivity of a capacitive sensing device having a sensor capacitor with a variable capacitance. The apparatus includes a measurement module and a processor. The measurement module is configured to determine, in response to a first electrical input signal to the sensor capacitor, a first quantity indicative of a first capacitance of the sensor capacitor and to determine, in response to a second electrical input signal to the sensor capacitor, a second quantity indicative of a second capacitance of the sensor capacitor. The processor is configured to determine a quantity indicative of the sensitivity of the sensing device based on the determined first and second quantity.
