Communication Electronics ECE145B/ECE218B - Winter 2011 University of California, Santa Barbara MW 3:30 - 4:45, ESB 1003 (Cooper Lab) ________________________________________________________________________ Course contents. See the syllabus below. The course explores the design and analysis of radio frequency circuits, systems and the corresponding measurement techniques. Receiver system performance, mixers, voltage controlled oscillators, and phase locked loops are studied this quarter. ECE145B and ECE218B are co-listed in the catalog. Graduate students should enroll in 218B. Prerequisite: ECE145A/218A or permission of instructor. You should be familiar with transmission lines, Smith Chart, matching network design, amplifier gain, stability, noise figure. You should also have a basic knowledge of the use of Agilent ADS simulation tools. Instructor: Prof. Stephen I. Long, 3221F Engineering Sciences Building, 893-3965, [email protected] Office hours: MW2 - 3 or by appointment. Teaching Assistant: TBA; Office hours (to be held in the lab) References: The primary references are the lecture notes and the supplemental readings. 1. ECE145B/218B reader. (Alternative, 6556 Pardall Rd, Isla Vista.). This and the lecture notes will be the primary source for reading material. 2. Lecture notes, data sheets, application notes, ADS simulation files and tutorials will be posted on the course web page: www.ece.ucsb.edu/~long/ I tend to update lecture notes as we go along, so don’t print them out before we need to use them. 3. T. H. Lee, The Design of CMOS Radio-Frequency Integrated Circuits, Second Edition. Cambridge Univ. Press, 2004. I have selected this textbook that is an excellent reference. This book gives lots of insight but is weak on analysis. For those of you who are truly interested in the subject, it will prove to be a valuable investment. I will pick a few chapters from the book for reading during the quarter. Tools: Each lab group will be provided with a toolbox. The components and tools (expensive! handle with care) will be checked out by the ECE electronics shop. You will be responsible for returning these in good working order. Your BARC account will be charged for anything missing.. Reserve Book Room. Homework solutions will be placed on the RBR library web site: eres.library.ucsb.edu. There will be other readings and reference materials available there as well.2 Grading. The grading for seniors and graduate students will be separate. Graduate students taking the course will have more difficult assignments. The final is on Tuesday, June 9, 4-7pm. The grade for this course will be based on the following: Lab Projects 40% (lab1: 5%; lab2 20%; lab3 15%) Final 30% Midterm 20% Homework 10% Laboratory projects: # project Start Checkout Report due 1 Large signal amp and mixer characterization 1/5 1/24 2 VCO 1/26 2/16&17 2/18 3 PLL Frequency Synthesizer 2/23 3/10&11 3/14 Group presentations on one of the design projects will be required. Laboratory: The lab is in room 5162D. It will be accessible by card key. You may work in teams of two (preferred) or three (only if absolutely necessary) for the lab projects. A single report for the team will be sufficient. Project checkout. Design projects (Labs 2 & 3) must be demonstrated to the TA or instructor to verify that all specifications are met. You will need to make an appointment with the TA when you are ready to checkout. At the end of the quarter you will need to give a presentation on one of the design projects. Notebooks: Each student will be expected to maintain a lab notebook. Pages should be numbered and entries dated that document activity on the lab projects. Handwritten and computer plotted or generated measured data should be kept in the notebook. Keeping a sequential record of your work is an important discipline to acquire. Its purpose is twofold: 1. It provides a written record of your design process that can help you recall effective solutions to design problems and can help you avoid making the same mistakes again. 2. Many companies make lots of money on patents. New ideas must be documented by written, sequential, dated records in order to qualify for patent. Patent applications are very time sensitive, and properly documented notebooks play a central role in establishing date of concept. (In most cases, a bound notebook is required, but computer generated data is more easily included in an open notebook. Since you won’t be filing for a patent on our projects, it is ok to use a 3 ring binder, but do number and date pages). The notebook can contain circuit analysis work, design alternatives, ADS printouts, diagrams, measured data, or anything that seems relevant at the time. Incorrect or ineffective approaches and ideas should not be erased. You may want to refer back to something previously done. Lab Reports: Writing ability is a vitally important skill for an engineer. Your ability to clearly and concisely present your work in a formal manner to those who sponsor it, or the ability to clearly describe a proposed plan of action in order to obtain the necessary funding will play more of a role in your success as an engineer than most of you would imagine. Unfortunately, many engineers haven't made the effort to3 learn the necessary skills. Formal lab reports on the design projects will be required in order to help you improve your writing and communication skills.1 Grading Standards The standards for grading of the design projects are as follows. Please refer to the report format below to understand expectations. Seniors A Project meets all expectations. Report is well organized and written. A- , B+ Project comes close to meeting expectations; report is well organized and written, or the project meets expectations but the report is lacking in one component. B Project comes close to meeting expectations; report is lacking in two components. B - , C+ The project is adequate, but is poorly documented in the report. C, C - Project doesn't work or is incomplete. F Project bursts into flames during demo and burns TAs hand, or no project and report is submitted. Graduate Students A Project exceeds expectations. Report shows evidence of exceptional understanding. Innovative approaches were successfully employed at some point in the design. A- Project meets all expectations. Report is well
