Apparatus and methods of de-convolution for multi-phase scans of an array of electrodes are described. One programmable circuit includes a sequencer to initiate a multi-phase transmit (TX) scan of an array of electrodes to obtain capacitance data. The capacitance data is stored in one or more storage devices as convoluted capacitance data. The programmable circuit also includes a digital circuit block to read the convoluted capacitance data from the one or more storage devices, de-convolve the convoluted capacitance data to obtain de-convoluted capacitance data, and store the de-convoluted capacitance data in the one or more storage devices.

Hardware de-convolution block for multi-phase scanning

An embodiment of a method for detecting noise for a capacitance sensing panel may comprise generating an input signal based on a noise signal, performing a series of measurements for measuring capacitances from a capacitive sensor sensitive to the noise signal, and controlling timing for at least one of the subconversions based on the input signal.

Noise detection for a capacitance sensing panel

Method and apparatus for automating noise reduction tuning in real time

A system and method for synchronization of touch-panel devices is described. In one embodiment, the system includes a first controller device configured to control operations of a first portion of a touch-panel device such that the first controller device is further configured to generate a single master timing signal. The single master timing signal is configured to synchronize operation of the first controller device and a second controller device that is configured to control operations of a second portion of a touch-panel device.

System and method for synchronization of touch panel devices

Apparatuses and methods of hardware de-convolution for multi-phase scanning of a touch arrays are described. One apparatus includes a memory device configured to store a capacitance map including convolved capacitance data. The convolved data are results of multi-phase transmit (TX) scanning of a sense array with multiple TX patterns. The apparatus further comprises a de-convolution circuit block coupled to the memory device. The de-convolution circuit block is configured to de-convolve the convolved capacitance data with inverses of the multiple TX patterns to obtain capacitance data for a de-convolved capacitance map.
