Abstract
A novel experiment is presented which makes use of injection-lockable bipolar oscillators to measure on-chip coupling between integrated inductors. The experiment is fast, accurate and unique In that no matching, probe de-embedding or calibration is necessary as the ratio of two on-chip signals is measured to yield the results. Theoretical and simulated models of injectionlocked oscillators and inductor coupling are discussed and compared to results measured using the test chip to Validate the experiment. Results indicate about -55 dB of Coupling between two inductors spaced 175 pm apart. K e p m d Coupling Circuits, Electromagnetic Coupling, Inductors, Injection Locked Oscillators.
