英文摘要	In a spiral transformer, couplings between the coils are interlaced and correlative, and are difficult to independently extract from limited network parameters. in this article, we present a method for directly extracting model parameters including mutual inductances and port-to-port capacitances one by one. in the method, by leaving unmeasured ports short-circuited or open-circuited on the wafer, we transform a 4-port transformer into four 2-port networks for obtaining adequate measurement data, enabling us to extract all the '2-'-like model parameters independently. we adopt this method into the modelling of a 5:5-turn spiral transformer fabricated in 0.18 m cmos technology. finally, comparisons between electromagnetic (em)-simulated results, measured results and model-simulated results demonstrate that our method is accurate and reliable.
