The Fast-speed Calculating Method of Integrated MicrostripTapered Transmission Lines and the Property Analysis

Integrated tapered transmission lines are widely used in the active circuit modules as mstching elements and fast-speed analysis method is the key of circuit CAD. The new method given in this paper is that the simulating of properties is converted to solving a set of differential equations . Dividing the horizontal range (O,L) into N sections and integrating the equations over each section by linearly simulating the main network parameters, more faster iterating equations are obtained. In this method the secton number N needed is small and so the time spended is reduced greatly. Finally using this method the respomses of several characteristic parameters are calculated and property's analysis are given.
