Final exam. (Monday, May 17, 2004, 8-10a.m., CSS2324 ): Close-book, written exam. Bring a calculator. Put your personal belongings away beyond easy reach. No cell phones. No wireless equipment allowed, such as PDA, computer, etc.

Final examination topics:

1) One problem on single MOSFET amplifiers (CS, CS+Rs, CG, and CC configuration). As usual, be familiar with the dc analysis for voltages and currents everywhere, and the small signal ac analysis for input impedance, output impedance, and voltage gain.

2) One problem on Bode plots: given a tranfer function, which is already packaged in a polynomial form with known zero's and pole's, be ready to draw the (amplitude and phase) Bode plots.

3) One problem on CMOS inverter. Various aspects.

4) One problem on synthesizing a CMOS digital circuit: using the PUN and PDN concept, put together n-MOS and p-MOS transistors and implement a given logic function, such as a NOR gate.

5) And several other problems on digital circuits and simple concepts

 

Midterm examination (Wednesday, 3/31/04, room 2324, CSS building): Close-book, written exam. Bring a calculator.

Two circuits (out of four possibilities, including CE, CE/Re, CB, and CC amplifiers) for their dc (currents and voltages everywhere) and ac analysis (Rin, Rout, Av, and Ai). The difficulty level is the same as those in homework and textbook examples. No Bode plots this time --- we will use them in the final exam.
