Abstract
Sensor electrodes are coupled, in a first configuration, to input channels of a processing system. The sensor electrodes are used to acquire a measurement of current. In a second configuration that is different from the first configuration, the sensor electrodes are coupled to the input channels. The sensor electrodes in the second configuration are used to acquire a capacitive resulting signal. Positional information is determined using the current measurement and the capacitive resulting signal.
