Operational Amplifier, OP-Amp as inverting and non-inverting amplifier, OP-Amp as average, substractor, integrator and differentiator


  • Basic knowledge of Electronics


An amplifier is an electronic device which can amplify a weak electrical signal. Operational Amplifier is one of the important part of modern working electronics. The opamp is employed in various devices. Basics logic gate operations, RC circuits, Wien bridge circuits are some of the circuits in which an opamp may be used. A standard opamp has two terminals; the inverting and non-inverting. Electronics usually demands a proper understanding of circuits. Appropriate circuits are drawn to explain the different uses of opamp.

A systematic approach of this topic is presented in this lecture series. The topic of opamp is very extensive, but considering the essence of this course, some of the important topics are discussed. In this course the students will learn about the basics and use of one such device known as the Operational amplifier. The lecture is divided into two sections.

Section 1: This section discuss the basics of opamp along with its representation and circuit details.

Section 2: The application of opamp are discussed. The use of Op-Amp as inverting amplifier, non-inverting amplifier, substractor, average, differentiator and integrator is explained.

This course is primarily aimed at students who are in electronics or advanced physics. The course can be helpful for both undergraduate and post graduate students.

I have been in the field of teaching Physics for more than 10 years now. During this tenure I have taught Physics at different levels: matriculation level, Higher secondary level, Under graduate level and Post graduate level. I have been actively involved in research since 2011 which covers my PhD tenure at NIT Meghalaya, India and Post Doc experience at Shandong University, China. In the process of upgrading myself I have been disseminating Physics lectures in the form of online lectures.
