ANALOG ELECTRONICS LABORATORY

This lab is intended to give the students a practical experience in working with semiconductor devices such as junction diodes, bipolar junction transistors (BJTs), MOS field effect transistors (MOSFETs) and op-amps, and examines the design and operation of important circuits that utilize these devices. This laboratory integrates the theory taught in the basic course and helps the students to apply their knowledge of electronic circuits. An additional objective is to provide some practice and experience with relevant software tools for electronic circuit simulation.

Objective:

In this laboratory, students have to perform the experiments of Analog Electronics Engineering for the first time. Training in this laboratory is done mainly through excellent hardware set up as per the WBUT syllabus. The purpose is to teach analog circuit design theory and to give the student an understanding of the factors governing the behavior of electronic circuits. Topics covered also demonstrate the need for strong electronic component in other scientific and engineering fields.
