Course Outline and Policy

Description

This course introduces the basic analog building blocks and quantifies their performance parameters. More advanced circuits are derived from these basic building blocks. Concepts of feedback and stability are introduced to enable analysis of complex circuits. The course also includes a self-learning lab component in which the students are expected to learn circuit simulation and design tools such as LTSpice, Eldo, Cadence Analog Suite etc. A design project is an essential component of this course.
Postcondition On the completion of this course the students will be able to:
1. Have a basic knowledge of the fundamental concepts of active circuits and their analysis techniques.
2. Particularly understand the theory and operation of circuit components and circuits such as Current Mirror, Linear Amplifier, Differential Amplifier, OPAMPs etc.
3. Acquire the ability to solve, analyze, design, and simulate moderately complex MOS based circuits.

Evaluation Following components are part of the overall evaluation:
