1. A programmable circuit comprising:

  • a sequencer to initiate a multi-phase transmit (TX) scan of an array of electrodes to obtain capacitance data, wherein the capacitance data is stored in one or more storage devices as convoluted capacitance data; and

    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.
