Abstract
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.
