Abstract
An electronic assembly including a plurality of electrically conductive elements separated by insulative material and a digital FM demodulator circuit coupled to some of the electrically conductive elements. The FM demodulator circuit having an FM detector circuit and a DC drift reducing circuit. The FM detector circuit has a detector input and a detector output that is the output of a comparator that is AC coupled to the rest of the FM detector circuit, the detector input receiving an input signal. The DC drift reducing circuit is electrically coupled to the detector output of the comparator, the DC drift reducing circuit detecting a DC drift of the detector output, the DC drift reducing circuit being additionally coupled to an input of the comparator, the DC drift reducing circuit substantially eliminating DC drift at the output of the FM demodulator circuit.
