The Use of Engineering Program coupled with a Practice to Understanding in the Subject of Engineering Electronics

Abstract

This research project is the academic research for undergraduate student in engineering, faculty of engineering, Rajamangala University of Technology Rattanakosin (RMUTR). The research is to improve the basic knowledge of B.Eng. student about the subject of electronic engineering. The research methodologies have tried to be consistent with theoretical contents, guiding the student to understand the lessons. The student software can be downloaded at the following http://www.cadence.com/products/orcad/pages/downloads.aspx. Two major methodologies can be provided in this project, including the software and hardware parts. The contents are focused on the principal properties of diode, the some deviated properties of operational amplifier (OP-AMP), bipolar and filed effect transistors. For more details, the many diodes are studied about DC, switching, and small signal characteristics. An OP-AMP is concerned about an input bias current, offset input voltage, its effect and correction, slew rate, and power bandwidth. With the use of bipolar junction transistor (BJT), we present about the DC-characteristic, hybrid model, transfer function, and gain. Finally, the input and output characteristics and amplifier’s gain are then discussed. With the benefits of the research project, they make student the attention and understanding of the subject contents. The lecturers can improve the students with the basic knowledge based on the research project. In addition, the researcher has also prepared a pre-test study to determine the limits of each student for planning the next lesson.
