HARDWARE DE-CONVOLUTION BLOCK FOR MULTI-PHASE SCANNING
摘要
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.
