EL422

EL422 - CMOS analog IC design
The purpose of this course is to learn to analyze and design CMOS analog integrated circuits. Some fraction of all wired or wireless communication hardware has to have analog electronics (which will include amplifiers, A/D and D/A converters, modems, PLL circuits, and so on). Knowledge of analog circuit design is, therefore, indispensable for a communications engineer.

This course will broadly cover the following topics: Analysis, design theory and simulated design of CMOS op-amps; D/A and A/D converters; and PLL circuits (if time permits).

The course content includes :-
Physics of MOS transistors; dc and ac transistor models for circuit simulation.

Current mirrors and single-stage amplifiers: Simple CMOS current mirror, common-source and common-drain amplifiers, high Rout mirrors; cascode amplifier; differential amplifier; high gain amplifier; two stage operational amplifier analysis and design.

Advanced current mirrors and opamps: Folded cascode opamp; current mirror opamp.

A/D and D/A converters: Ideal converters; quantization noise; decoder-based, binary-scaled and hybrid D/A converters; integrating, successive approximation, flash and other A/D converters.
