'Soft Computing' Methods in Microwave Active Device Modeling

摘要

In this work, the signal and noise behaviors of a microwavetransistor within its operation domain (CT,V_{DS}, I_{DS}, f) aremodeled by the Artificial Neural Network (ANN) and Fuzzy Logic System(FLS) without using any information on the microwave circuit theory . A worked example is presented where the same data is employed for bothmodels selected from the manufacturer's data sheets. Performances ofthe FLS and ANN models are compared and conclusions are drawn.
