Abstract:
Self capacitance touch circuits to cancel the effects of parasitic capacitance in a touch sensitive device are disclosed. One circuit can generate a parasitic capacitance cancelation signal that can be injected into touch sensing circuitry to cancel the parasitic capacitance. Another circuit can adjust the phase and magnitude of the parasitic capacitance cancelation signal based on characteristics of channels in the touch sensing circuitry so as to fine tune the parasitic capacitance cancelations. Another circuit can drive a guard plate and touch panel electrodes so as to cancel the parasitic capacitances between the panel and the plate and between the electrodes.

Claim (Index 13):
A method of operating a touch sensor panel system, the method comprising:\n while first circuitry is sensing a self-capacitance of first one or more touch electrodes of a plurality of touch electrodes of the touch sensor panel system:\n driving second one or more touch electrodes of the plurality of touch electrodes at a first voltage configured to cancel parasitic capacitance between the first one or more touch electrodes and the second one or more touch electrodes; and \n driving a guard plate at a second voltage configured to cancel parasitic capacitance between the first one or more touch electrodes and the guard plate; and \n providing a cancellation signal to the first circuitry, the cancellation signal configured to reduce an effect of remaining parasitic capacitance on the self-capacitance of the first one or more touch electrodes, sensed by the first circuitry, that is not cancelled by the second circuitry.
