Abstract: A method and an apparatus for canceling EM coupling are provided. The apparatus includes a ring structure at least partially surrounding an EM circuit. A negative transconductance circuit is coupled to ends of the ring structure. The negative transconductance circuit is configured to cancel an EM coupling to the EM circuit at a frequency. The method includes generating a plurality of settings for a negative transconductance circuit and tuning the negative transconductance circuit to one of the plurality of settings for the negative transconductance circuit to cancel an EM coupling to an EM circuit at a frequency.
