Seventh  Week - February 26 - March 2

Midterm Results:

The average was 51.8 and the standard deviation was 13.6. You may roughly compute you grade as follows. Take the average as the middle of the B- range and add 1/6 of a standard deviation to get the score required for a B. Then add 1/3 of a standard deviation to get B+, A- and A. Similarly a B- requires the average minus 1/6 of the standard deviation and each 1/3 of the standard deviation gives C, C-, D+, etc. This yields D = 31.4, C = 45, B =58.6 and A= 72.2. Overall the exam was a little long given that much of the material was relatively new to you. More details will be posted under exams.

Office Hours this week for Professor Neureuther M11, Tu none, W 9, Th none, F 11, F 2.

This modification is due to  participation in the SPIE Microlithography conferences in San Jose this week. 

Discussion Sections: 

Examples of phasors and their use in circuit analysis. Examples of Bode (frequency response) plots and methods for sketching them quickly. Applications of phasors and Bode plots to op-amp circuits and simple MOS amplifiers to determine the dominant gain and bandwidth performance.

Laboratories: 

Experiment #5 MOS Device Characterization: This week you will make prelab SPICE simulations of the measurement configurations that will be used in lab. These circuits are related to the techniques illustrated in HW problem 4.3. See the Prelab information on the lab news web page under updates.

Homework:

The homework is being graded on a scale of 0-10 and you must achieve an 8 or better in the initial grading to have mastered the homework on schedule. Questions about grading should be emailed to kobe@uclink4.berkeley.edu
