Description
:
This is the second course of two course stream for Electronics Design and Analysis. The sequence of
these two courses together is geared to develop the ability to analyze and design electronic circuits,
focused towards implementing the basic building blocks into functional Analog ICs
EE221 is the second course, which builds on the foundations taught in the first course EE216. This
course introduces the students to knowledge that is required to understand the working of the Analog
Integrated Circuits (ICs).
The first part of this course introduces the basic MOSFET (and BJT) Transistor cell that is used as a
basic building block in IC circuits. This followed by special multiple transistor configurations like
cascade and cascade configurations, which are used for their special gain and frequency response
characteristics while building complex circuits. The student is also introduced to the Current Mirror
circuits including current steering circuits, which form an important part of most ICs.
The Differential and Multistage Amplifiers are discussed next. In this context the MOS and BJT
differential pair is discussed in detail followed by Non-Ideal Characteristics of Differential amplifiers.
The Multistage Differential amplifier is also introduced focused on the determining various important
circuit design parameters. Subsequently the student is made to build on his basic understanding of
Frequency response of BJT and extend it to MOS Frequency response followed by analysis of the
frequency response of different multistage circuits using MOSFETS and BJT.
The next topic of study is the concept of feedback in electronics amplifier circuits and the student
learns about the four feedback configurations and their implementations. The feedback amplifiers are
then studied for stability using Nyquist criterion and bode plots.
The last part of the course deals with Output Stages and Power amplifiers. The classes of power
amplifiers namely Class A, Class B abnd Class AB are studied for delivering power to load in an
efficient manner.
