Abstract :
A Design-Oriented FET model in conjunction with an appropriate design procedure for distributed amplifiers is presented. The advantage of including the effects caused by FET parasitics in a newly defined simple unilateral FET circuit to be utilized in the conventional distributed amplifier design procedure allows an accurate prediction of the low-frequency gain and the 3-dB cutoff frequency. The simplicity of this formulation and a set of generalized design charts provide an interesting opportunity to designers. Comparisons among different experimental data from literature and the results obtained by this theory confirm the validity of the Design-Oriented FET model and the effectiveness of the given graphical design method
