Abstract
Aspects generally relate to tuning a guard ring in an integrated circuit. A guard ring with a gap surrounds a circuit. The level of isolation provided by the guard ring at a particular frequency can be adjusted by coupling a tuning circuit cross the gap of the guard ring. If the circuit in the guard ring is an inductive circuit the level of inductance at a particular frequency can be adjusted by selecting the appropriate tuning circuit across the gap of the guard ring.
