Abstract: A system is disclosed. The system can comprise drive circuitry included in a first component of the system, the drive circuitry configured to drive a first touch electrode on a touch sensor panel. The system can also comprise a driving line configured to couple an output of the drive circuitry to the first touch electrode. The system can also comprise a feedback line configured to couple the output of the drive circuitry to an input of the drive circuitry, wherein a first end of the feedback line is coupled to the input of the drive circuitry at the first component, and a second end of the feedback line is configured to be coupled to the output of the drive circuitry at a second component, different from the first component, of the system.

Abstract: A system is disclosed. The system can comprise dynamic drive circuitry configured to drive a plurality of electrodes on a touch screen. The system can also comprise a switching circuit configured to selectively couple the dynamic drive circuitry to one or more of the plurality of electrodes. The system can also comprise a display circuitry configured to selectively update a plurality of display pixels on the touch screen. The dynamic drive circuitry can be configured to set its output based on which of the plurality of electrodes are selectively coupled to the first drive circuitry and which of the display pixels are updated by the display circuitry.
