Abstract
Decreasing the cost of a touchpad by avoiding the cost of simultaneously measuring all signals from sense electrodes by using a limited number of measuring circuits to accomplish noise reduction and de-ghosting of signal data to thereby obtain the precise location of multiple fingers on a touchpad, wherein the touchpad separates the drive electrodes into groups to thereby provide a means for obtaining granular location information for de-ghosting the touchpad, and wherein overlapping measurements are made of groups of sense electrodes to obtain data that is separated in time to thereby obtain an averaged signal for each electrode and thereby reduce sensitivity to noise.
