Study of Electronic Circuits with Operational Amplifiers Using Interactive Environments for Design and Analysis

This paper presents computer models designed for undergraduate students on the engineering study programs of higher education institutions to help them learn about linear circuits with OpAmp. The models allow for the study of inverting and non-inverting amplifiers with OpAmp, different variants of transimpedance amplifiers with photodiodes. Using the NI Multisim Analog Devices Edition software environment allows for experimental research like working with kits in university laboratories. The developed electronic tools allow lecturers to formulate individual projects for each student, and students - to independently conduct research on the given project. The results of the experimental studies also are shown and discussed in the paper. They were tested in the training of students in the discipline of analog circuitry at the Faculty of Physics and Engineering Technologies, University of Plovdiv Paisii Hilendarski and in optoelectronics at the Department of Electronics, Faculty of Electronic Engineering and Technologies at Technical University of Sofia in conducting online training during quarantine COVID- 19.
