<p>PROBLEM TO BE SOLVED: To provide a circuit design method for obtaining high calculation precision with less parameter in a large signal simulation. SOLUTION: In the design method of a circuit using a field effect transistor, the field effect transistor is shown as a two terminal non-linear circuit model source constituted of the parallel connection of a current source 6, where a gate terminal is opened in a use frequency band and whose current changes dependently on voltage, and a capacitor 5 between a source and a drain. Then, element parameter in a large signal operation whose amplitude of input voltage, which is decided by the impedance of the circuit and input voltage, is large is obtained.</p> |
