Abstract: A processing system including an amplifier configured to generate, from multiple spatial-common-mode-processed signals, a spatial common mode estimate and multiple feedback signals. The processing system includes multiple charge integrators configured to obtain resulting signals from the capacitive sensor electrodes, each of the resulting signals including a spatial common mode component and a residual noise component. The charge integrators generate multiple spatial-common-mode-processed signals by mitigating the spatial common mode component and the residual noise component in the resulting signals using the feedback signals. The processing system includes a programmable gain amplifier configured to determine the spatial common mode estimate.

Abstract: The embodiments described herein provide devices and methods that facilitate improved input device performance. Specifically, the devices and methods provide improved resistance to the effect of interference on input devices, and in particular, to the effect of unison noise on proximity sensors that use capacitive techniques to generate images of sensor values. The devices and methods provide improved resistance to the effects of interface by using images of sensor values and one or more profiles of sensor values. An image of sensor values is combined with one or more profiles of sensor values to produce a modified image of sensor values, the modified image having reduced errors due to noise. This reduction in errors due to noise can improve the accuracy and performance of the input device.

Abstract: A processing system includes a transmitter module, a receiver module, and a determination module. The transmitter module is configured to drive a first contact, a second contact, and a third contact of a first transmitter electrode, wherein the first contact is disposed between the second contact and the third contact. This produces a first voltage gradient between the first contact and the second contact, and produces a second voltage gradient between the first contact and the third contact. The receiver module receives, with a first receiver electrode, a first resulting signal including effects of the first voltage gradient, and to receive, with a second receiver electrode, a second resulting signal comprising effects of the second voltage gradient. The determination module determines positional information for an input object located within a sensing region based on the first resulting signal and the second resulting signal.
