Classification: CPC G | IPC G

Claim 13:
14. The method of claim 13, wherein:
Ci_i includes an ith base self-capacitance (Cs_i) corresponding to ith display noise capacitively coupled onto the ith channel from the display panel and an ith touch capacitance (Ctouch_i) that changes responsive to presence of a touch event local to the ith channel;
Ci_j includes a jth base self-capacitance (Cs_j) corresponding to jth display noise capacitively coupled onto the jth channel from the display panel and a jth touch capacitance (Ctouch_j) that changes responsive to presence of a touch event local to the jth channel; and
at least a portion of the ith and jth display noise is common-mode noise on the ith and jth channels, such that the first and second branch voltages include a common-mode component corresponding to the common-mode noise.
