1. A capacitance-sensing circuit comprising: a channel input associated with measuring a capacitance of a unit cell of a capacitive sense array; and a capacitive hardware baseliner coupled to the channel input, the capacitive hardware baseliner to generate a baseline current based on a time constant of the channel input associated with the measuring of the capacitance of the unit cell of the capacitive sense array using a baseline capacitor, wherein the capacitive hardware baseliner to provide the baseline current to the channel input to provide a charge for a sense capacitor, wherein a change in the charge of the sense capacitor that is provided by the baseline current indicates a presence of a touch object proximate to the unit cell.
