Text Books: Design of Analog CMOS Integrated Circuits, Behzad Razavi, Published by Mc Graw Hill Education, Second Edition, ISBN: 9780072524932

Fundamental circuit techniques and design issues for mixed-signal integrated circuits. Topics include switched-capacitors, analog-to-digital and digital-to-analog conversion including oversampled coders, along with both system-level and circuit level modeling using VerilogA.

This focus of this course is on data converter circuits and systems. Commonly used architectures such as flash, two-step, pipelined, algorithmic, successive-approximation and oversampling delta-sigma modulators are discussed in details. The effects of circuit non-idealities are analyzed and various system and circuit techniques will be discussed to enhance the performance of these converters.

The course Covers analog circuit layout, and verification of CMOS circuit with use of computer-aided design tools such as Cadence. Topics covered are analog MOSFET models, current sources, references, amplified design, nonlinear analog circuits, dynamic analog circuits, ADC, and DAC.

This course examines the physics of microelectronic semiconductor devices for silicon integrated circuit applications. Topics covered include: semiconductor fundamentals, p-n junction, metal-oxide semiconductor structure, metal-semiconductor junction, MOS field-effect transistor, and bipolar junction transistor. The course emphasizes physical understanding of device operation through energy band diagrams and short-channel MOSFET device design. Issues in modern device scaling are also outlined.

Analog amplification; small-signal modeling of analog circuits; differential amplifier topology; BJT, MOSFET, and JFET differential amplifiers; frequency response and time-dependent circuit behavior; feedback and stability; multistage and power amplifiers; active filters and oscillators; use of CAD in modern transistor circuit design.
