Test #2
Name:__________________
Show all work. Clearly indicate final answer(s).
Cheatsheet must be turned in with test or a zero will be given for the entire test!
1. (40 pts) For the circuit to the right, if R1=1.5kΩ,
R2=7kΩ,
RE=100Ω,
RC=RL=1kΩ,
β=180,
VBE=0.7V, VCC=5V and all capacitors are infinite
and ideal, determine:
a. the Q-point;
b. Vopp;
c. Pout(ac);
d. dc power delivered by the source.
2. (25 pts) Given RC=RL=2kΩ, RE=200Ω, β=200,
VBE=0.7V, VCC=15V and all capacitors are infinite
and ideal:
a. select R1 and R2 for maximum possible
symmetric current swing;
b. determine the maximum symmetrical
output voltage swing.
3. (35 pts) Given R1=8kΩ, R2=2kΩ, RE=RL=1kΩ,
β=80, VBE=07V and VCC=15V:
a. determine the maximum symmetrical
output voltage swing ;
b. sketch the ac & dc load lines;
c. calculate the conversion efficiency of the
amplifier.
Extra Credit: (25 points max) For the circuit to the right, determine
the β of the transistor at saturation when RB=100kΩ, VBE = -0.7V and
VCE(sat) = -0.2V.
