Final Exam:, Tuesday June 11, 8  11 a.m.
The final will be in three rooms: map is here
Last Name Starting with letters AK: Chemistry 1171: (seats 100)
Last Name Starting with letters: LR: Phelps 2524: seats 55
Last Name Starting with letters: SZ: 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.

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,

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/(voltsecond) NMOS, 200 for PMOS 
MOS saturation drift velocity

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

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.
