This course is dedicated to the development of expertise and
confidence in the subject area of electronics. As indicated by the
course name it is the second course in the electronics sequence. So
the policies and syllabus make the assumption that you already have a
semester's worth of insight in the subject area.

Electronic II is an upper level course, and it would be a good idea
to take a read of this perspective
document and its commentary.
Email is the operational link to your instructor. And it is also
the vehicle by which you will receive most of your runtime information,
such as homework assignments, corrections, new postings and updates.
When enrolled in the course you are also instantiated in the class
alias, usually within the first few days of the semester if not
earlier. If for some reason you find that you are not receiving email
you might check with the ECE office or send email to
email@example.com to ascertain the reason why you do not exist.
If you have registered late you may find that you are in purgatory and
your existence is delayed by circumstance. But if you do not appear to
have an electronic presence within 2-3 days of the beginning of the
semester you might ping the admin services in order to advance and be
Since homework will, in large part, not be drawn from the textbook
but exist as postings on this class website, it will be in a somewhat
dynamic state, subject to minor modifications and wholesale changes.
Homework from past semesters is not valid, and if solutions from old
homework postings should appear, then it may will cease to become
homework and then become evidence in a hearing, for which your
perceptions of academic dishonesty will have to be reviewed and you will
have need to rethink your career choices. Your professor would rather
not have to deal with this sort of situation.
Electronic submissions: Subject to
professor discretion, it is likely that pSPICE homework may be called
for submission electronically .
A particular demand of pSPICE submissions is that you should
be concise. You are expected to parse your pSPICE output
files and submit only those parts that are relevant to the question being
addressed. This is a demand, not a request, and penalties are assessed
for excess inclosures. And they add up quickly.
Whether electronic or hardcopy, pSPICE submissions should be
accomplished using MS Word or an equivalent utlity to format the output
into a compact and concise (and readable) form, usually 2-3 pages
at most. All electronic submissions should be converted to .pdf format
, since the acrobat reader is the only utility that allows markup without
compromising the original document.
Due dates for electronically submitted homework are the same as for
Homework postings: Subject to wholesale changes

If for some reason you do not feel secure with the pSPICE circuit
simulation utility you might take a few moments and walk through these
tutorials. They are slow and patient, and will help to get you started
and into the more important aspects of pSPICE that are needed for expert
- Tutorial #1:
Getting Started - pSPICE Schematics editor.
- Tutorial #2:
Execute pSPICE and invoke the PROBE (output display) window.

MOSIS parameters into generic MOS part. Example: I-V characterstics for short-channel transistor.
If you do not have a copy of the student version of pSPICE, go get
one at the
ORCAD/Cadence (updated) site. It should be a straightforward download
and install. If for some reason this copy is not friendly (sometimes
also called 'vendor improved') then you can obtain an old reliable
