A method of processing an electrical signal includes: capturing, via at least one main lead, an electrical signal; capturing, via at least one noise lead, a noise reference signal, wherein the at least one noise lead includes at least one conductive loop formed on a plane; receiving, by a processing device, the electrical signal and the noise reference signal; and processing, by the processing device, the electrical signal to cancel the noise reference signal from the electrical signal to obtain a processed electrical signal.
