 Ve311 Lab #2

Note:
(1) Please use A4 size papers.
(2) The lab report should be submitted online individually.
(3) Use Proteus 8.10 for simulation before the lab session. In the Proteus
library, you should be able to find all the components used in the schematics.
The lab report must include both the simulation and measurement
results.
1. [Common-Emitter Amplifier]
(a) [40%] Design and build a common-emitter amplifier in Proteus and
on the breadboard which has a voltage gain Aυ > 10, using npn BJT
2N3904. Plot VOUT vs VIN . (Hint: First choose an appropriate RC .
Second, perform DC sweep to find out a VIN at which the magnitude
of slope is more than 10. At the same time, make sure the BJT is in
the forward-active region. If not working, change for another RC and
repeat the DC sweep analysis again.)
(b) [30%] For Vin = VIN + 0.01sin(2π102
∙ time) , plot Vout = VOUT +
υout vs time. Confirm that the amplitude of υout is equal to 0.01 ×
Aυ.
(c) [30%] For Vin = VIN + 0.01sin(2π107
∙ time) , plot Vout = VOUT +
υout vs time. Is the amplitude of υout still equal to 0.01 × Aυ? If not,
explain the possible reasons.
