INTERLEAVED SCANNING FOR CAPACITIVE TOUCH SENSORS

A touch sensing circuit includes: a plurality of sensor channels; a controller coupled to the plurality of sensor channels, the controller configured to: map the sensor channels to sensor nodes, the sensor nodes forming a plurality of interleaved lumped sensors, where at least two of the interleaved lumped sensors include a common sensor node; scan, during a scan period, the interleaved lumped sensors to detect one or more touch inputs; and responsive to detecting one or more touch inputs, determining a location of at least one touch input.
