Abstract
A touch pad controller includes a voltage generator and a selector circuit. The voltage generator has a plurality of output terminals, each of the plurality of output terminals for being coupled to a corresponding pad of a plurality of capacitive touch pads. The voltage generator provides a predetermined voltage to each of a plurality of touch pads in a predetermined sequence. The selector circuit has a plurality of input terminals. Each input terminal of the plurality of input terminals is coupled to an output terminal of the plurality of output terminals of the voltage generator. The selector circuit sequentially couples each output terminal of the plurality of output terminals of the voltage generator to a touch pad shield for charging the touch pad shield to the predetermined voltage.
