About the course
This course will introduce you to one of the most important components in Electronics, which is an Op-Amp. In this course, you will learn about the Op-Amps circuits and how an Op-Amp works as a difference amplifier. Also, you will learn about instrumentation amplifiers followed by understanding the bode plots which determine the frequency response of the Op-Amps. After that, you will learn about the application of Op-Amps in designing filters which are commonly known as high-pass, low-pass, band-pass and band reject filters. Next, you will learn about precision rectifiers, which also make use of Op-Amps followed by Schmitt Triggers. Finally, the course concludes with Sinusoidal oscillators.
After completing this course, you will be able to:
- Understand the fundamentals and working of operational amplifiers.

Professionals: All working professionals from the core electronics industry.
Why learn Op-Amps?
Since the introduction of the first IC op amp, huge improvements have been made in both semiconductor processing and circuit design. For roughly 40 years, IC manufacturers have employed these improvements to design nearly "ideal" amplifiers. In the present world of precision amplifiers, small-signal designers concern themselves with critical factors such as low supply current, low offset, low noise, and low bias current. Significant improvements have been made in all aspects of process technology. These improvements allow amplifier design engineers to take the maximum performance and functionality from every technology. The demand for the design engineers has also increased due to these developments in the field of core electronics engineering and will continue to grow in the coming future.
