Analog Circuits

This 132-lecture NPTEL course from IIT Madras goes deep into analog circuits, starting with power amplifiers and nonlinear circuit behaviour. The lectures are labelled by week and lecture number, which gives a clear sense of how the material is paced across the course.

Small-signal thinking

A large part of the early material is about incremental analysis: graphical methods first, then equations, then the small-signal equivalent circuit. Diode large-signal and small-signal models, followed by two-port nonlinearity and gain, show the same approach applied to real components.

Who it is for

• Electronics students who want analog design explained from the device model upward.
• Learners who found amplifier small-signal analysis confusing and want a second, slower treatment.
• Anyone preparing for analog electronics questions in a competitive exam, where two-port models come up.
