- 1.
- Construct the multi-stage amplifier circuit in Fig. 2.14.
Use R1=100K, R2=10K, RC = 10K, RE1=1K, RE2=10K.
Using the information above, determine the values of the
DC voltages VC1, VB1, VE1, VB2, VE2, and
VC.
- 2.
- Measure the DC values VC1, VB1, VE1, VB2, VE2, and
VC. Compare your measured values with the calculated ones.
- 3.
- Theoretically calculate the small signal gain of the circuit
- 4.
- Input a 100kHz signal with amplitude of 0.1V into the circuit and
measure the voltage gain. Compare the measured value with
one you calculated above.
- 5.
- Now, add a load resistor RL=10K and measure the gain again.
How would the gain change if the second stage were not there?
