Aplicación web para la simulación de circuitos amplificadores básicos y refuerzo del estudio no presencial

Abstract

The present work is focused on basic electronics subjects and specifically on the understanding and interpretation of amplifier circuits based on bipolar junction transistors. In this context, students acquire the skills to identify the different configurations, algebraically analyze the circuit and obtain the necessary parameters to characterize the behavior of the amplifier. However, from a practical point of view, students have more difficulties in understanding and interpreting the connection between the theoretical concepts and the real behavior of the circuit. In this sense, the objective of this research work is to develop and provide students with an online simulation tool that allows them to interact with the amplifier circuits studied in the theory class and understand how they behave with different configurations, component values or signals. The incorporation of circuit simulation in theory class has been investigated by the authors themselves during several courses. Compared to other courses, in which these simulations were not introduced, an improvement was observed in the obtained results. Additionally, students positively valued the inclusion of these simulation tools in the theory class and considered that it helps them to better understand the theoretical concepts. From this survey, it was deduced that students would like to have these same simulation tools outside the classroom in order to complement the non-face-to-face study.
