Claim 9:
10. A non-transitory computer readable medium storing instructions that, when executed by an electronic device including a touch sensor panel including one or more sense electrodes surrounded by one or more drive electrodes, cause the electronic device to perform a method comprising:
applying one or more drive signals to the one or more drive electrodes during touch sensing using drive circuitry;
applying one or more second drive signals to one or more second drive electrodes using the drive circuitry, the one or more second drive signals having a different phase from a phase of the one or more drive signals; and
sensing one or more voltages of the one or more sense electrodes using sense circuitry, the one or more voltages indicative of one or more mutual capacitances between the one or more sense electrodes and the one or more drive electrodes during the touch sensing.
