I. INTRODUCTION
The goals of this course are:
(1)
Understand the physics of electrical
components, including inductors, FETs and digital ICs
(2)
Familiarize you
with the basic electronics used in commercial electronic instruments
(3)
Accurately measure the time dependence
of voltages and currents in electrical circuits
(4)
Apply mathematical techniques to
analyze electrical circuits and circuit diagrams
(5)
Be able to construct, troubleshoot and
operate various electrical circuits
(6)
Be able to design and build a prototype device that accomplishes a
specific purpose
In
the future, your work may involve sophisticated electronic instruments and it
will be important to have some understanding of their principles and
limitations. You may also encounter applications requiring you to design
custom electronics.
The
physics aspect of electronics is both interesting and
useful. Semiconductor devices require quantum mechanics for a proper
explanation of their behavior, but many things can be understood using some
basic math and fundamental principles of electricity. We will concentrate
on practical knowledge and applications of electronics, and
also cover some of the microscopic theory where it is appropriate.
The course introduces the latest technology of semiconductors and optical
electronics.
We
will explore the physics underlying computers and our modern electronic world. The
course focuses on: principles of semiconductor devices (diodes, transistors,
integrated circuits, LEDs, photovoltaics); analog techniques (amplification, AC
circuits, resonance); digital techniques (binary numbers, NANDs, logic gates,
and circuits); electronic subsystems (operational amplifiers, magnetoelectronics, optoelectronics); and understanding
commercial electronic equipment.
The
lab experiments are designed to investigate the properties of discrete and
integrated devices and use them to design and build circuits. They
provide experience in laboratory techniques: setting up equipment, making measurements,
analyzing data, and describing the results. The laboratory instructions
will be less detailed as the course progresses, as you become more confident in
designing and carrying out the experiments.
II. TOPICS
This course covers basic DC
and AC circuit analysis, digital electronics, and analog
applications, including op-amp amplifiers and optoelectronics. The following
topics will be covered:
Basic
Lab Tools (multimeter, oscilloscope, function generator, power supply, etc.)
Circuit
Analysis and Design
Physics
of Semiconductors, Diodes and Transistors
Transistor
Circuits
Operational
Amplifiers
Magnetoelectronics
Optoelectronics
(optical electronics)
Digital
Circuits and Logical networks
III. LAB NOTEBOOK
An electronic is
required. Students are requested to use Microsoft OneNote for their
e-notebook.
All raw data is to be recorded in digital file as it is taken. Set up tables with appropriate columns in
Excel. You may find that after taking some data that you have made a
mistake. In that case, DO NOT DELETE THE TABLE, simply begin a new table
and insert some of the previous data - never erase seemingly unwanted data, as
in hindsight it may be useful.
It
is very important to Plot appropriate data as it is
taken. These initial plots can be very crude. This allows
you to see where additional data points are needed and which data points need
to be retaken.
IV. LAB WORKSHEETS
Each student must submit an independent printed Lab Worksheet
or Lab Report.
Lab Reports should include diagrams of the apparatus,
tables and appropriate plots. The length of the report must not exceed 4-pages, thus allowing
you focus on the more important aspects. The writing and general format of the
reports are intended to provide a clear and straightforward description that
contains the important information without extraneous (and often boring)
minutiae.
The
following ˝publication˝ format is highly recommended: Template 2372
