Multistage BJT Amplifier (Multisim Experiment)
Equipment
1. Multisim
2. Brain
Materials
1. Pencil
2. Paper
Procedure
1. In Multisim, construct the multistage amplifier circuit in Figure 7-1 above.
2. Measure IB, ICQ, ? and VCEQ of amplifier stage. (You can show all values at one time
using digital meters if you wish.)
3. Using the oscilloscope to show Vin (Channel A) and Vout (Channel B), determine the
measured overall voltage gain, AV(OA).
4. Using the peak input voltage (Channel A), determine Iin(pk) and using peak output
voltage (Channel B), determine Iout(pk). Use these two values to determine the measured
current gain, Ai(OA).
5. Use your measured voltage gain and current gain to determine the measured power gain,
AP(OA).make sure you the calculations
