Methods and apparatus for performing capacitive touch sensing and proximity detection

Embodiments include methods and apparatus for performing capacitive touch sensing and proximity detection. Electrode selection circuitry establishes a first connection with an individual electrode of a plurality of individual electrodes in order to receive one or more first signals indicating a state of the individual electrode, and establishes second connections with a proximity electrode that comprises multiple ones of the plurality of individual electrodes in order to receive one or more second signals indicating a state of the proximity electrode. A processing system performs a first analysis on the first signals to determine whether to perform a first updating process for an individual electrode baseline value, and performs a second analysis on the second signals to determine whether to perform a second updating process for a proximity electrode baseline value. In an embodiment, the first analysis and the second analysis are different from each other.
