Automated Impedance Matching Network Design Process and Design Examples with SPICE Performance Evaluation
This chapter examines how each of the broad and narrow band impedance matching schemes examined in Chaps. 2 and 3 is automated as C computer language executables. Almost all of the C computer language executables generate the corresponding impedance matching subcircuit design, formatted as a text SPICE input netlist. Simulation Program with Integrated Circuit Emphasis (SPICE) is the industry-standard simulation tool for evaluating the performance characteristics of any electrical or electronic circuit. Each generated SPICE netlist includes a test bench to evaluate the root mean square (RMS) delivered from signal source to load, as well as estimate the reflection coefficient, insertion loss and standing wave ratio (SWR) for each broad or narrow impedance matching subcircuit. Utility C computer language programs compute the RMS values for a generated data set, as well as the reflection coefficient, insertion loss and SWR.
