ECE145b (undergrad) and ECE218b
(graduate)
DO NOT GO TO THE SCHEDULED LAB HOURS during the first week of classes. The laboratory/design content of the class is run on an independent basis. Design projects are assigned and a due date is given. Students work in the lab constructing and testing their designs, working in the lab at whatever time they find most suitable to work.

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.
Mid-term Exam: Tuesday February 13, class period (same room as lecture)
Dead week: March 11-15
Last Lecture: March 14
Final Exam: Tuesday 4 - 7 p.m. March 19

The
office hours are for the TA to give you guidance with your projects and
assignments. On weeks when lab projects are due, or even being worked on,
the regular office hour times will not held, and the
TA will instead be in the lab to guide you.. The TA will email the class to
set up times for these. They are also
posted below, but check with the TA's emails if these two sets of records don't
agree. |

Please contact the TAs regarding HW solutions or grading.
On weeks when students are working on lab projects, the hours below, in the lab, supersede the TA offic hours above.

The primary course reference material is the online lecture note set.
*Optional* texts for this class are
…optional for 145B: : Hooman Darabi, Radio Frequency Integrated Circuits and Systems
Either 1st or 2nd edition would be fine.
…optional for 145B: Stephen I Long, Communication Electronics: RF Design with Practical Applications using Pathwave/ADS Software
…optional for 218B: Sorin Voinigescu, High-Frequency
Integrated Circuits
https://www.cambridge.org/core/books/highfrequency-integrated-circuits/4BF00791FE2320D7FE4368E8F2424E4D
Please feel free to purchase either of these texts, or neither 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.

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.

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.
