Abstract
A single-layer touch-sensor device having a calibration mechanism coupled therewith is described. Included is a charge measurement circuit coupled, by a pair of electrical traces, with a slider of the single-layer touch-sensor device. A pair of calibration capacitors is included, each calibration capacitor coupled, between the slider and the charge measurement circuit, with one of the pair of electrical traces. A pair of connection switches is also included, each connection switch coupled with one of the pair of calibration capacitors.
