The transmission characteristics of various fabricated square and circular on‐chip transformers are studied and compared in this article. According to the proposed lumped‐element equivalent‐circuit model and the measured broadband S ‐parameters, both self and mutual inductances are extracted accurately, which facilitates further study of the coupling coefficients and loss mechanism of on‐chip transformers. © 2004 Wiley Periodicals, Inc.
