Prerequisites: EE 325; EE 325K, EE 339, and EE 363M won't hurt, but are not required

Objectives: The intrinsic speed/frequency performance of semiconductor devices has increased dramatically in the last decade and a half. For instance, today you can buy a MMIC (monolithic millimeter / microwave integrated circuit) amp with performance that ten years ago would probably have cost at least ten times more. Due to the extremely rapid growth of the Personal Communications Services (PCS) industry, the demand for knowledge about rf circuits and microwave wireless systems has also increased dramatically. Finally, as digital systems strive for speeds that require GHz effective bandwidths, microwave issues may begin to influence even microprocessor design!

Course Outline:

As a class goal, we will try to prove or disprove the following conjecture:

The physical world is fundamentally unfriendly towards complex (read: generally useful) electronic systems which operate at frequencies in excess of 100 GHz or speeds faster than 10 psec.

I first proposed this in class six years ago, and I've seen little since then to suggest we change this goal....

 

Class Projects: You must complete a class project, which will count for 30% of your grade. The project will consist of the identification of a state-of-the art high frequency/speed SYSTEM, and a detailed, critical examination of relevant literature to identify what components limit the performance of this system. You will then prepare a written discussion of your findings, as well as presenting a DETAILED, BUT SHORT, oral explanation to the class. You will be expected to explain your findings in language we can all understand; I will not accept "conventional" explanations which consist primarily of fancy jargon. Before making your class presentation expect to spend at least two hours with me, with a return visit to clarify any problems (and I guarantee I will find something to object to) identified in your first meeting with me. Class presentations will begin in mid-April.

Grades

Your grades will be based upon performance on homework, exams, and the class project. Homework will be assigned approximately weekly; credit for late homework will be reduced at a rate of 10% per class the work is late.

The weighting for different areas is:

 

Homework 15%

Mid term exam 25%

Class project 30%

Final 30%

100%

 

The worst-case grades will be based on:

A 100-90% of total points available

B 80-89%

C 70-79%

D 55-70%

F 0-55%

OFFICIAL UNIVERSITY CALENDAR AVAILABLE AT: http://www.utexas.edu/student/registrar/98-99long.html

LAST DAY TO DROP: 4TH DAY OF CLASSES (Jan. 22); BETWEEN THEN AND Feb. 15 MUST GO TO DEAN'S OFFICE; AFTER Feb. 15 THERE MAY BE AN ACADEMIC PENALTY; after March 29 drops allowed by UT only for extreme non-academic reasons. Feb. 8: Last day a student may submit notice of planned absences in the spring semester for the observance of religious holy days. (See General Information, chapter 4, for requirements.)

Course Evaluation: University and optional in-house survey during last week of class.

 

Policy on CHEATING:

You are expected to do your own work at ALL times. I expect you will often discuss assignments, but you MUST do your own ORIGINAL written work. Any evidence of cheating or plagiarism* will be treated as grounds for FAILURE in the class.

*"A CASE OF PLAGIARISM

"May is a second-year graduate student preparing the written portion of her qualifying exam. She incorporates whole sentences and paragraphs verbatim from several published papers. She does not use quotation marks, but the sources are suggested by statements like '(see . . . for more details).' The faculty on the qualifying exam committee note inconsistencies in the writing styles of different paragraphs of the text and check the sources, uncovering May's plagiarism.

"After discussion with the faculty, May's plagiarism is brought to the attention of the dean of the graduate school, whose responsibility it is to review such incidents. The graduate school regulations state that 'plagiarism, that is, the failure in a dissertation, essay, or other written exercise to acknowledge ideas, research or language taken from others' is specifically prohibited. The dean expels May from the program with the stipulation that she can reapply for the next academic year." [ URL: http://www.nap.edu/readingroom/books/obas/contents/misconduct.html#Plagiarism ]

"A broad spectrum of misconduct falls into the category of plagiarism, ranging from obvious theft to uncredited paraphrasing that some might not consider dishonest at all. In a lifetime of reading, theorizing, and experimenting, a person's work will inevitably incorporate and overlap with that of others. However, occasional overlap is one thing; systematic use of the techniques, data, words, or ideas of others without appropriate acknowledgment is another."

Policy on use of class news group:

We have a newsgroup set up on the net for this class at utexas.class.ee397k. This newsgroup is for class business ONLY. Homework or questions from lecture are appropriate topics for discussion. THE NORMAL RULES OF CIVIL DISCOURSE SHOULD BE FOLLOWED AT ALL TIMES. I will read the postings regularly, and enter into discussions as appropriate.

 

THIS SCHEDULE IS WILL BE MODIFIED ONCE I SURVEY THE INTERESTS OF THE CLASS!
