Abstract: Techniques are described for using an alternating-current-mode (AC-mode) bridge for low-noise self-capacitor sensing in a capacitive touch panel array integrated with a display panel. Each channel of the array has a self-capacitance (Ci) that changes responsive to presence or absence of a local touch event local. Pairs of channels are read out differentially by coupling pairs of channels to branches of an AC-mode bridge. The AC-mode bridge includes current sources that drive each branch (and thereby each channel) with a sinusoidal current, manifesting a branch voltage on each branch based on the self-capacitance of the branch. The branch voltages are used to generate an output voltage. The sinusoidal current is controlled by comparing a driver signal with feedback from the branches, so that common-mode noise on the channels becomes a common-mode component of the sinusoidal currents and is rejected in the generation of the output voltage.
