<p>A detection circuit for return electrode monitoring is disclosed. The detection circuit includes a transformer operatively coupled to a pair of split electrode pads, wherein the transformer is configured to transceive a return electrode sense signal. The detection circuit also includes a first switch coupled to the transformer and a neutrally-referenced second switch, wherein the first switch and the second switch are disposed on a single die. The detection circuit further includes an operational amplifier coupled to the first switch and the neutrally-referenced second switch. The operational amplifier is configured to subtract a noise signal from the return electrode sense signal.</p> |
