Linearization of amplifier using differential transformation

This paper presents a novel linearization scheme for the pulse amplifier based Differential Taylor Transformation. It is shown that nonlinear properties of transistor results to strong dependence of the risetime from effect amplitude. The problem of risetime stabilization in nonlinear amplifiers is considered. The numerical-analytical minimization approach of the temporary parameters independent from pulse effect amplitudes have been offered. Condition of invariance of the response risetime to the source signal amplitude is determined. Modeling of the amplifier stage is carried out. The aim is to give an insight into Differential Taylor Transformations as the power method with its advantages.

I. Background

Recently the great successes in the pulse generation, shaping, amplification and control of parameters are achieved. However the theoretical boundaries are not achieved up to now [1]. The main reason is difficulty of the microwave device synthesis using of classical methods because of the classical models in the RLC basis and the operator functions has high order. Besides dimensions the active and passive elements become comparable with wavelength. The dependence of parameters of pulse signals (delay, form, amplitude) is followed from dimensions of elements and their connections. Therefore researches of the signal transformation processes and the high-speed problem complex decisions, based on the system theory are necessary required.
