Abstract: An apparatus of one embodiment includes a sensor and a controller. The sensor has first and second electrodes separated by an insulator. The controller includes measurement circuitry, a processor, and a memory comprising logic. The logic is operable to disconnect the second electrode from the measurement circuitry, induce a current on the second electrode by applying voltage to the first electrode, apply charge to the second electrode, connect the second electrode to the measurement circuitry after applying the charge to the second electrode, and determine a capacitance value associated with the second electrode.

CPC classification number: G06F3/044 , G06F3/0416
Abstract: In one embodiment, an apparatus for detecting a touch. The apparatus includes a touch sensor that includes a first plurality of electrode lines and a second plurality of electrode lines. The apparatus also includes a touch sensor controller coupled to the touch sensor. The touch sensor controller is operable to apply a respective voltage pulse simultaneously to each of the first plurality of electrode lines, measure a respective signal at each of the second plurality of electrode lines, and detect a touch based on the measurement of the respective signals.
