Метод побудови широкосмугового двотактного підсилювача постійного струму на відбивачах стуму

Abstract

This fundamental research presents an exhaustive and multi-level analysis of the structural and functional organization of a novel architecture for two-stroke (push-pull) direct current amplifiers (DPPS), constructed using complex internal selective feedback loops and advanced multi-node current reflectors.[1, 1] The study encompasses a deep theoretical review of the evolution of transistor amplification paths, from basic symmetrical architectures to state-of-the-art topologies capable of functioning under intense common-mode interference and power supply voltage fluctuations. Based on the theory of nonlinear electrical circuits, detailed descriptions are provided for the static transfer characteristic and the corresponding linearity errors under thermal drift conditions. A comprehensive explanation for analyzing the dynamic characteristics of basic DPPS circuits is obtained, taking into account package parasitic capacitances and semiconductor degradation effects.
