Week 6 Lab Solved

Description

• Part A:
  1. Analyze the circuit or the amplifier shown in Figure 1. Determine the voltages V_B, V_E, V_C, V_BE and V_CE. Using the beta value of 100, determine the gain of the amplifier (A_V). (Include 20% tolerances for resistors and capacitors).
  2. Construct the circuit shown in Figure 1 on the breadboard using the hardware parts.
  3. Using the jumper wires, screw driver and screw terminal connector, connect the board to NI MyDAQ Instrument Device.
  4. Using the function generator in NI ELVISmx Instrument Launcher, provide the voltage (Vin). Use channel AO0 pin on the NI myDAQ Instrument Device to provide this voltage. Make sure the frequency is 1 KHz frequency.
  5. Using +15V pin out on the Instrument Device provide the supply voltage VCC.
  6. Perform the DC Analysis by disconnecting the capacitors and measuring V_B, V_E, V_C, I_B, I_E and I_C.
  7. Place the capacitors back and using pin AI0 on the NI myDAQ Instrument Device, measure the required voltages: V_B, V_E, V_C V_BE, V_CE.
  8. Measure the currents: I_C and I_E using the Multimeter.
  9. Use AI1 on the NI myDAQ Instrument Device to measure the load voltage V_RL. Record the measurements and compare them with the calculated values in step 1.
  10. Using the input voltage V_in, base voltage V_B and load voltage V_RL, determine the gain of the amplifier (A_V).
