Abstract: Disclosed herein include an input device, processing system and methods for touch sensing. In one embodiment, an input device is provided that includes a plurality of sensing elements arranged in a sensor pattern and a plurality of conductive routing traces. Each conductive routing trace is conductively paired with a respective one of the plurality of sensing elements. The sensor routing traces are configured to reduce an RC load of the corresponding paired sensing elements compared to a base RC load of a plurality of base electrodes arranged in a base pattern that is identical to the sensor pattern. Each base sensor electrode is conductively paired with a base routing trace. The base sensor electrode and paired base routing trace have a size that is identical to a size of the paired sensing elements and conductive routing trace. The base routing trace terminates at the base sensor electrode to which the base routing trace is paired.
