+  ECE137AB Circuits and Electronics

This 2-quarter sequence has 2 components. We spend about 75% of our time in a design-oriented coverage of transistor analog electronics. The remaining time is spent covering transient and frequency- response of RLC networks. We also will try to cover lots of feedback, filter,  and linear systems theory so as to complement ECE130ABC.

-  Prerequisites

ECE 2A, 2B, 2C Circuits and Electronics.     ECE132 Semiconductor Device Physics

ECE130A.         ECE137A is a prerequisite for ECE137B (of course)

If you have received a C- or below in any of these courses, or have a GPA below 2.0, you should arrange to see the instructor immediately

-  Texts:

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




Design projects, not set experiments, will be assigned as the lab content of the course. The labs will be open, and you are free to work on your projects whenever the lab has open hours.  The lab design projects are highly independent in nature, and your work should be creative, independent, original, and analytically rigorous.  You will make a appointment at a specified time to check off the lab project in the presence of the TA. The lab is closed to further lab construction or project debugging during these times.  The project must be working and available for check off at the time of the appointment; it is otherwise graded as late with associated penalties. Upon check-off, the circuit is handed in to the TA, and the TA in return provides a signed check-off sheet of recorded measurement values to each design team. This check off sheet is then included by the students as a part of the design report, due usually 1-3 days after the check off period.


Design teams are groups of two students. Larger groups are not permitted.


There are no parts boxes in the lab. Parts for the lab can are obtained from the electronics shop on the 1st floor of engineering. Since they are not open evenings or weekends, reasonable advanced planning is required in terms of purchasing parts.  Things you should purchase, one set-up per group of students: A tool and part box (Tackle box or Tupperware),Wire stripper and pliers , Solder less bread board, Soldering Iron (20-30 Watts), and solder, soldering heat sink clips, a small sponge (cleaning the iron tip), Vector board (perforated circuit board), a set of test leads for the digital voltmeter, 2 oscilloscope cables, and "flea clips"-insertable soldering terminals for vectorboard (optional, makes circuit construction easier and neater). While these items can be bought at Radio Shack or Dow/Marvak, the electronics shop on the 1st floor of engineering 1 will generally be much more economical. For desoldering, please consider purchase desoldering wick. You must purchase lead-free solder from the electronics shop. Do not purchase solder elsewhere, as it will likely be tin/lead solder, which is toxic. "Solder-sucker" desoldering tools are not permitted in the lab, as they disperse a dust of solder granules into the air  and onto surrounding surfaces. If you are also foolishly using tin/lead solder, you will then poison yourself.  Again, use lead-free solder from the shop, and use desoldering wick to remove solder.

Homework  Assignments

Homework sets will be due, at the times posted on the web, in the homework boxes in the center stairwell on the 5th floor of engineering 1. Late homework cannot be accepted as it interferes with the need to post solutions and return graded homework assignments quickly. Solutions will be  posted on the class web page a few minutes after the due date. About 20% of the problems will be graded in detail, with the remainder graded correct/incorrect.

Copying work and other honesty issues

You are expected to work independently on both your problem sets and your lab projects. Significant sharing of design details on the lab projects is a violation of academic standards.  Students are expected to keep their eyes on their own exams: students may expect to receive an exam grade of zero if they are observed to be looking at other student's examination papers.

Grading (approximate)

Lab 25%          Problem Sets 10%       Mid-term 25% Final 40%


Mid-term and final exams will be closed book. 2-Page amplifier crib sheet allowed on both mid-term and final. 2 Pages of student notes allowed on mid-term, 3 pages of student notes for the final.
