Abstract

For investigation of the impact of initial bias of an amplifier stage under collector current cutoff conditions on linearity of its amplitude response, the author proposes to use the accuracy of the polynomial model of the stage transfer function and to study the opportunities for unlimited expansion of the approximation domain of the threshold model. The results of theoretical and experimental investigations are presented.
