Abstract: This application is directed to a capacitive sense array including a two-dimensional array of capacitive sense elements. Each capacitive sense element is formed by a respective intersection of (i) a respective row electrode in a first electrode layer and (ii) a respective column electrode in a second electrode layer. Each column of the capacitive sense elements includes two or more interdigitated column electrodes. Each row electrode forms two or more rows of capacitive sense elements at intersections with the column electrodes.

Abstract: A circuit comprising an oscillator configured to provide a first output signal in response to one or more input signals. A divider circuit may be configured to receive the first output signal of the oscillator circuit and to present a signal having a second frequency at a second output. A frequency comparator circuit may receive the second output signal and an external signal having a third frequency and may present a third output signal representing control information. A processor circuit may be coupled to the oscillator circuit, the divider circuit and the comparator circuit. The processor circuit may control the frequency of oscillation of the first output.
