Abstract
Apparatuses and methods of frequency hopping algorithms are described. One method monitors a signal on one or more electrodes of a sense network at a first operating frequency and detects noise in the signal at the first operating frequency. The method then switches to a second operating frequency, based on said detecting, for scanning the electrodes to detect a conductive object proximate to the plurality of electrodes, wherein a constant integration time is used for one half-period when scanning the electrodes at both the first and second operating frequencies.
