Course Description

       This first course in Electronics will give the students an insight of designing and analysis of
different Electronic circuits consisting of basic Electronic devices and the fundamental principles
of these Electronic devices. First the basic Electronic devices and components are being covered in
this course. Then analysis of different Electronic circuits is carried out. The aim is to provide an
understanding of the methods and techniques used in the analysis of Electronic circuits and to
simulate them using some simulation tools. The course will include lectures and case studies.

Course Objectives

This course is a pre-requisite of “Electronic devices and circuits” and other courses. By the end of
this course, students should have attained the knowledge as per the course contents and be able to:
      To solve diode and BJT circuits specially input and output loops of BJTs using KVL.
      To apply the knowledge of diodes, capacitor charging and discharging and determine the
       behavior (output waveforms) of clipper, clamper, half/full- wave rectifier and zener diode
       circuits.
      To design simple power supply.
      To use basic SPICE models of diodes and BJTs in simulations
