Final Exam:, Tuesday June 11, 8 - 11 a.m.

The final will be in three rooms: map is here

Last Name Starting with letters A-K: Chemistry 1171: (seats 100)

Last Name Starting with letters: L-R: Phelps 2524: seats 55

Last Name Starting with letters: S-Z: Phelps 3505: seats 60.


There will be a small # of extra points awarded for students who arrive at the exam and are seated 10 minutes before the beginning of the exam.

This is needed because of the large # of late arrivals to the mid term and the resulting disturbance to those taking the exam.

Suggested Reading: Spring 2013

comment: Sophomore circuits texts seem to contain an enormous amount of material, and favor repetition and a large set of examples  over focus and emphasis on fundamental principles. It can be overwhelming to try to read these texts in detail. The principles of circuit and signal analyis covered in ECE2C are covered in the online lecture notes and in the problem sets. For your reference, I have attempted to correlate the weekly lecture material to that of the material in Thomas and in Sedra and Smith,

Problem sets: Spring 2013

Problem sets are due Mondays at 5PM in the ece2c HW box in HFH.

Problem sets are to be worked individually, not in groups. Submitted problem sets showing strong evidence of copying will be graded as zero.

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.

lambda (MOSFETS)

0 in DC calculations

1/(10 V) in AC calculations

MOS channel mobility

400 cm^2/(volt-second) NMOS, 200 for PMOS

MOS saturation drift velocity

10^7 cm/s NMOS, 5*10^6 cm/s PMOS

Additional study problems

These problems  may prove helpful in studying for the final exam (2013). Do please also review in detail the problem sets and lecture notes.

Additional  Material

 

CAD Resources

CAD programs are not required for the class, but are useful as a learning tool.

 

The ECE department does not endorse any particular product or differentiate between any product or its competitors.  However, we have purchased a license for MultiSim v9, and this program is installed on the computers in the ECE2 lab

 

CircuitMaker Student Edition is a free download, although it is no longer supported by the original developer.  It still works fine under Windows XP.
