Modeling of Nonlinear Circuit using Volterra Series
AbstractVoterra series method was used to analyze signal distortions. During application of this method there is no need to form differential equations, which characterize parametric and frequency properties of non-linear circuits. Volterra series method was applied to analyze the nonlinearities of common emitter circuit. Modeling of nonlinearities was performed. Fundamental components of signal distortions were evaluated. Equation system in operator form was written for non-linear circuit, after solving which, the analytical expressions of Volterra series kernels were obtained. Laplace transform of kernels was used to determine the magnitudes of signal distortion components. The output signal constant component and first harmonic variations in dependence on the parameters of the input signal over a frequency range were presented.
