Abstract :
A problem of stabilization of the pulse risetime depending amplitude in nonlinear FET amplifiers is considered. Modelling of the amplifier sections is carried out. It is established that nonlinear properties of FET results to dependence of the risetime from effect amplitude. The computing minimization of the temporary parameters independence from pulse effect amplitude has been proposed. The aim is to give an insight into differential-Taylor transformations as the power method with its advantages.
