ENEE312H Spring 2006
1. Diode: 3.2 and 3.4, due next Thursday (2/9/2006) Solution1
2. DC bias for bipolar transistor: 5.76, 5.77, 5.78, due next Thursday (2/16/2006) Solution2
3. DC bias for bipolar transistor: 5.79, 5.90, due next Thursday (2/23/2006) Solution3
4. Small signal analysis of bipolar transistor amplifiers: Solution4
A. Be familiar with table 5.6 (by re-deriving the results and understand the physical meaning and circuit characteristics)
B. 5.104, 5.105, and 5.124.
C. Reproduce by yourself the pspice simulation shown in Fig. 5.82 (Output voltage as a function of frequency). The full circuit is shown in Fig. 5.81, as part of the example 5.21. Turn in your pspice schematic (circuit diagram) or text program, and plots showing the voltage gain, and, separately, the output phase, as a function of frequency. The frequency should cover the range of interest.
5. Due March 28, Tuesday Solution5
[This part is for your reading assignment: (a) Derive the Miller theorem (page 578) by yourself --- details are in the textbook. (b) Read and get familiar with Appendix E. (c) Read/understand section 6.6.]
(a) Transfer function: T(s)=100×s/[(1+s/106)×(s+104)], s=jw, and w goes from 1(1/s) to 1010(1/s).
Inspect the transfer function and identify the AM, TL(s), and TH(s). Plot the Bode plots, including the amplitude vs. frequency and the phase vs. frequency, for (1) the midband gain; (2) the low frequency transfer function; and (3) the high frequency transfer function.
(b) 5.130 (a typical problem in analysis)
(c) 6.68 (CS high frequency performance)
(d) 6.70 (CE high frequency performance)
*Note: for 6.68 and 6.70, try do the complete analysis by yourself (do not refer to the existing formula in the textbook)
(e) 4.54 (MOS with an active load)
(f) 4.77 (typical MOS problem)
6. Due May 2, Tuesday Solution6
(a) 8.26 (identify feedback topology)
(b) 8.29 (series-shunt)
(c) 8.37 (series-series)
(d) 8.48 (shunt-shunt)
7. Due May 9, Tuesday Solution7
(a) 11.16 ring oscillator
(b) 11.17 ring oscillator
(c) 11.26, DRAM operation
