1. A detection circuit for return electrode monitoring, the detection circuit comprising:

  • a transformer operatively coupled to at least one pair of split electrode pads, wherein the transformer is configured to transceive a return electrode sense signal;

    at least one first switch coupled to the transformer;

    at least one neutrally-referenced second switch, wherein the at least one first switch and the at least one second switch are disposed on a single die; and

    an operational amplifier coupled to the at least one first switch and the at least one neutrally-referenced second switch, the operational amplifier being configured to subtract a noise signal from the return electrode sense signal.
