Introduction of Integrated Circuits
Research Interests and Focus
• VLSI (Very-Large-Scale-Integration) Design
and CAD (computer-aided design ) with an
emphasis on analog/RF optimization and test.
•Circuit simulation, parallel CAD algorithms,
design and analysis of power and clock
distribution networks.
•Interconnect and timing analysis, statistical
circuit analysis and optimization.
My Research Assignment
Objectives:
• Have basic understanding on CMOS Circuits.
• Use CMOS Circuits to design a circuit system which has
basic logic functionalities.
• Analyze the circuit functionality and performance through
hand (graphical) analysis.
• Verify the circuit through PSPICE simulation.

What is CMOS?
Complementary metal–oxide–semiconductor
CMOS is a major class of integrated circuits.
CMOS was also sometimes referred to as complementary-symmetry
metal–oxide–semiconductor (or COS-MOS).
The words "complementary-symmetry" refer to the fact that the typical
digital design style with CMOS uses complementary and symmetrical
pairs of p-type and n-type metal oxide semiconductor field effect
transistors for logic functions.
Two important characteristics of CMOS devices are high noise immunity
and low static power consumption. Significant power is only drawn when
the transistors in the CMOS device are switching between on and off
states.

What is the Pspice?
PSpice is a SPICE analog circuit and digital logic
simulation software that runs on personal computers,
hence the first letter "P" in its name. It is used in
electronic design automation. The name is an acronym
for Personal Simulation Program with Integrated Circuit
Emphasis. Today it has evolved into an analog mixed
signal simulator.

Summary:
focus on modeling basic CMOS transistor
behavior using simple switch models and more
sophisticated continuous models, and then
analyzing circuit functionality and performance
through hand (graphical) analysis and verifying
through PSPICE simulation.
My Research Assignment
Student Project
Student will be able to use PSPICE (downloadable) not only
to simulate circuit design process but also verify and analyze
their design.
