I have great pleasure to present this book on Analog Circuit Design, S.Y.B.Sc. Electronic Science -Semester IV EL-241: Paper-I. It is written as per the 2020 pattern, Choice Base Credit System (CBCS) syllabus of Savitribai Phule Pune University, Pune-411007 implemented from June-2020.

The author have tried his level best to simplify the difficult concept in electronic science with neat diagram and simple mathematical equation. 

The basics of electronics which is required to understand the concept of Operational Amplifier is covered. The understanding of IC-741 as Astable Multivibrator is made very simple by drawing the diagrams. The applications of Operational Amplifier IC-741 are made very simple.

Concept of negative feedback Types of feedback circuits: current shunt, current series, voltage shunt and voltage series, First sorder butter worth active filter Concept of Positive Feedback: Barkhaussain criterion, Oscillator circuits -Wien bridge, Phase Shift are explain in simple language and  very symmetrically.

I thank to Publisher IIP Publishing House (IPH) www.iiponline.org for helping me to publish this book.
