| Abstract: | This paper is concerned with the analysis of circular spiral inductor and transformer components used in MMIC's. Simple equivalent circuits of the components are given. The analysis includes computation of the values of inductance, capacitance and resistance in the equivalent circuits using the method of moments under quasi-static condition as well as finding "S" parameters of the components with network analysis. Routines "PCSI" and "PCST" which calculate the values and "S" parameters have been implemented. Theoretical results are compared with Typical measurement and reasonable agreement between the two is found. The maximum error is about 5% The method can be used to analyze components with an arbitrary number of spiral turns. |
