Winter 2021: ECE137A

 

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.

 

In 2021, we *expect* to have the first two weeks of lectures (and office hours) online, and *expect* to resume in-person classes in the 3rd week. We therefore *hope* to start the lab projects in the 3rd week. These plans may change.

Lab Hours and Design Projects

 

As of 1/1/2022, UCSB has deterimined that the first two weeks of Winter 2022 term will have online lectures and office hours. ECE137A normally starts its hands-on design projects at the beginning of the third week. If the online teaching period is extended beyond the second week, we will have to change our plans, but, for the time being, we plan on having three hands-on design projects this term.

 

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, working in groups of two (not three) constructing and testing their designs, working in the lab at whatever time they find most suitable to work.

 

During the week of that each lab project is due, and the week prior to this, the above TA hours will *not* be held. Instead, the TAs will be in the lab to provide you with guidance in the lab, at hours posted both here and on the lab door.

Lab Access During Lab Periods

Checkoffs will be in the lab, and will be by appointment. A signup sheet for lab checkoffs will be distributed by the TAs. Please see the TAs if you must change your appointment time. During the checkoff periods, the TAs are not available to provide you with guidance, and the lab is will be closed except to those checking off.

Missing parameters in assignments: Often a problem statement will omit to give certain parameter values. In those cases, use default values, as below. In some problems, you are asked to use data sheet values for device parameters. In those cases, be certain that the data is not on the data sheet before using these default values.

Textbook

The main text for the class is the online lecture notes- these are available via the links below.

 

You will also need to have a quality analog IC design text. If you don't have one, good choices include Fundamentals of Microelectronics, by Behzad Razavi, Microelectronic Circuit Design by R.C. Jaeger and T.N. Blalock, or Analysis and Design of Analog Integrated Circuits, by Grey, Meyer, and Lewis. The Grey/Meyer/Lewis text, in particular, is well well-focused without much unneccessary added material to distract you from the key subjects. These books can be purchased online from many vendors. Older editions have the advantage that used copies can be obtained at a lower price. Any of these books would be just fine.

 

Every textbook covers the material differently, as do the lecture notes. It helps to have several perspectives.

Lecture Notes

 

Please read each note set before attending lectures. It will then be much easier to follow the lectures !
