1. A method, comprising: measuring a mutual capacitance on a sense element of a sensing device using a modulation circuit, wherein the sensing device comprises a plurality of drive lines and a plurality of sense lines, and wherein the sense element comprises an intersection between one drive line of the plurality of drive lines and one sense line of the plurality of sense lines, and wherein the sense element is representative of a capacitor, and wherein the measuring the mutual capacitance on the sense element comprises: applying a drive signal to the one drive line using an excitation signal source; and sensing, by the modulation circuit, the drive signal on the one sense line to measure the mutual capacitance of the capacitor; switching the capacitor to be coupled and decoupled to a modulator capacitor of the modulation circuit using a plurality of switches, wherein the plurality of switches is controlled by a spread spectrum clock; and converting the mutual capacitance measured on the sense element to a digital value.
