Abstract

Open-circuit time constant method (OCTCM) is an important knowledge point in the course of Analog Electronic Circuit, and it is an important part of the knowledge system of “from Device to single-stage amplification, to multi-stage amplification, to integrated amplification, to feedback, to frequency response analysis”. Since OCTCM is universal in analyzing amplifier circuits, most textbooks and teaching materials mainly introduce the analysis procedure of OCTCM based on the two-port model, and give the conclusion that “when the existence of the main pole cannot be determined, the obtained high frequency cutoff frequency needs to be corrected by 1.14”. However, it doesn’t provide an analysis of the applicability of this conclusion. In order to solve the above problems, this paper first presents the definition, analysis principles, and methods for evaluating the error of OCTCM. Subsequently, it analyzes the frequency response of the double-pole amplifier circuit. On this basis, the analysis of the error of OCTCM is given, including the applicability analysis of the correction coefficient 1.14, the judgment of the dominant pole, and the discussion of other correction coefficients. By introducing the applicability analysis of this problem in the practical teaching, the paper aims to enhance students’ understanding of OCTCM and improve educational outcomes.
