OPAMP and Linear Integrated Circuits

OPAMP and Linear ICs are essential parts of Analog Electronic Circuits. Starting from signal amplification, and signal processing to system design, operational amplifier plays a vital role. There are different varieties of OPAMP available in the market with different characteristics and functionalities. Some of them are used for general-purpose applications, some are designed especially for signal amplification, etc.  The basic opamp discussion starts with 741 opamp IC which is fundamental to any OPAMP. This course covers the fundamentals of OPAMP, OPAMP circuits, and other linear ICs. This course is suitable for diploma, and undergraduate students, and electronic hobbyists interested in learning and designing OPAMP-based circuits. This course may be a fundamental step to understanding the essential theories to solve numerical importance for different competitive exams, GATE, and PSUs for Indian students.
