Op-Amp Practical Applications: Design, Simulation and Implementation

Op-Amp Practical Applications: Design, Simulation and Implementation. Instructor: Prof. Hardik J. Pandya, Department of Electronic Systems Engineering, IISc Bangalore. This course is a system design-oriented course aimed to provide exposure on applications of Op-Amps and its importance in the real world. Since analog circuits play a crucial role in the implementation of an electronic system, this course emphasis 0n complete system design with initial discussion on circuit design. As part of this course student can build analog systems using analog ICs and study their macro models. Below are some of the course outcomes. To expose the operation of the basic building blocks of analog system To understand and analyze the Op-Amps. To understand feedback techniques and its advantage Ability to design amplifiers using Op-Amps Ability to analyze and design filters using Op-Amps, To develop the skill to build and troubleshoot Analog circuits To develop the skill to build complete system using analog circuits.
