```									1/26   introduction to the syllabus
1/31   doping, impurity, Coulomb potential, donor, etc
2/2    pn junction dc IV curve and ac equivalent circuit
series resistance rd and parallel capacitors
derivation of the ac equivalent circuit
Table 3.1 shows several circuit models; Eq. 3.11 and 3.20
bipolar transistor dc IV curves in the common emitter configuration
Table 5.2 all equations must be understood and memorized
Early effect and Early voltage and output resistance
derivation of the "large signal" equivalent circuit
converting a biasing network by Thevenin's theorem
dc biasing methods: resistors as voltage divider, two power supply version
dc biasing by a collector-base resistor
derivation of the small signal equivalent circuit, particularly the transconductance,
r_pi, and r_e
obtain the ac small signal equivalent circuits: the pi model and the T model
start to use these two models in single transistor amplifier analysis: CE, CB, and CC
for input impedance, output impedance, voltage gain, and current gain
definition of zin, zout, av, and ai; CE amplifier analysis
voltage source: ac impedance=0
current source: ac impedance=
coupling capacitance ac impedance is often assumed to be zero

Table 5.5, the definitions
CE amplifier ac analysis
CE with emitter resistor, its ac analysis: again, Rin, Rout, Av, and Ai; the key is to
understand what's the difference from the CE amplifier without the emitter resistance
particularly the input resistance is now higher, the voltage gain smaller (feedback)

impedance in receiving high frequency pulses…
