Abstract
Apparatuses and methods of adaptive resolution circuits are described. One apparatus includes an input node coupled to a capacitance sense pin coupled to an electrode of a sense array and a capacitance-sensing circuit coupled to the input node and comprising an integrator configured to measure a capacitance with a first resolution. An adaptive resolution circuit is coupled to the capacitance-sensing circuit and the input node and is configured to selectively modify an integration capacitance of the integrator to set the integrator to measure the capacitance with a second resolution.
