Instructor

Prof. Mark Rodwell
Lectures: Tuesdays, Thursdays, 330-445PM, South Hall 1609

Office hours: Tuesdays, Thursdays, 2-3 PM, ESB 2205F
office hours are preliminary; will be adjusted to be consistent with student class schedules.

Lectures & Discussion Sections

(from http://my.sa.ucsb.edu/public/curriculum/coursesearch.aspx )

Main Lectures: Tuesdays, Thursdays, 330-445PM, North Hall 1111
Weekly discussion session: To be announced. In some weeks Rodwell will give a make-up lecture or design review in this time. Please reserve this time on your calendar.

Extra evening sessions (makeup for travel, lab preparation, exam review):

There may be dates during the term which I must travel. There will always be a substitute lecturer on those days, but I will also schedule make-up lectures to re-cover the material to ensure consistent coverage.

Lab Hours and Design Projects

The class design content will be in the form of a design project (circuit simulation and mask layout) and of a series of circuits you must design, construct on a PC board, and test. You do not need to attend the lab hours posted in the Schedule of Classes.

Rivera, Isaac

isaacrivera@umail.ucsb.edu

TO BE ANNOUNCED. Location: in the lab. You can also send him an email.

The office hours are for the TA to give you guidance with your projects and assignments. On weeks when lab projects are due, these will substitute. The TA will email the class to set up times for these.

 

Teaching assistant hours in lab

On weeks when students are working on lab projects, the hours below, in the lab, supersede the TA office hours above.

Textbook

The primary course reference material is the online lecture note set.

 

*Optional* texts for this class are

 

…optional for 145C: : Hooman Darabi, Radio Frequency Integrated Circuits and Systems

https://www.amazon.com/Radio-Frequency-Integrated-Circuits-Systems-dp-110719475X/dp/110719475X/ref=dp_ob_title_bk

Either 1st or 2nd edition would be fine.

 

…optional for 145C: Stephen I Long, Communication Electronics: RF Design with Practical Applications using Pathwave/ADS Software

https://www.amazon.com/Communication-Electronics-Applications-Publishers-Electronic-ebook/dp/B0CPL5YDJN/ref=sr_1_2?dib=eyJ2IjoiMSJ9.0bSc5gSIU96tOlizKqiYLzXMifrxz0EON1eshkyScco.UhWQXlNwfGmvug2nbA7hAQ0qHXbz-PbOEW-0Tg0ZHyg&dib_tag=se&qid=1704923018&refinements=p_27%3AStephen+Long&s=books&sr=1-2

 

…optional for 218C: Sorin Voinigescu, High-Frequency Integrated Circuits
https://www.cambridge.org/core/books/highfrequency-integrated-circuits/4BF00791FE2320D7FE4368E8F2424E4D

 

Please feel free to purchase any of these texts, or none of them.

 

Please learn to access / search IEEE Explore (accessible without charge from UCSB IP addresses or with a UCSB Web account with proxy settings). The technical literature is an excellent learning tool.

 

Wikipedia 's material on radios is often useful, though it can vary greatly in technical depth. Any information obtained from the internet should be verified against a primary technical publication.

Problem sets and design projects in the class use the Agilent ADS microwave IC design environment. Access to ADS can be either through accounts in the ECI lab, or via the microwave teaching lab on the 5th Floor of Harold Frank Hall. If you are member of a research group in the ECE dept, you may well also have access to ADS via your group's PCs or Workstations---ask your Professor.

Homework, Lab, and Exam Solutions (this year):

 These will be distributed by the TA using canvas or similar software.

 

Lab project: Spring 2024

Assignment: lab_2024.pdf

 

April 15: CAD layouts of printed circuit boards and block diagrams of transmitter due. Place your order of the transmitter printed circuit board on or before this date.

 

April 29-30: Check off in the lab of your functioning transmitter with the teaching assistant. You will also need to have assembled a PRBS unit at that time.

 

May 13: CAD layouts of printed circuit boards and block diagrams of receiver due. Place your order of the receiver printed circuit board on or before this date.

 

June 3-4: Check off in the lab of your functioning transmitter with the teaching assistant.

 

Given that this is the first year with this project, and the level of difficulty is not yet well understood, the level of complexity of the transmitter and receiver design is at the discretion of the students. ECE218C students will be expected to complete a more complex design than ECE145C students.
