Lab7 (1^st week) Report Instructions

• The lab report should be segmented in 3 parts:
  • BJT Inverter
  • BJT Inverter with Emitter Resistor
  • BJT Voltage Follower

   

• Inverter:
  • Plot VI curve for BJT with load line, show load line equation used.
  • Sketch (by hand, PSpice or any drawing program) the inverter circuit.
  • Plot Vout vs. Vin curve (Transfer Characteristics curve) for Inverter, show constant region range (Vinmin-Voutmax,Voutmin-Voutmax) and gain computed from slope.
  • Show Vinmidlle & Voutmidlle in constant region.
  • Show AC gain obtained from Oscilloscope readings, and VoutDC value, IoutDC equation and value.
  • Show Vin value to achieve Vout clipping, explain why clipping occurred at this value.

   

• Inverter with Emitter Resistor:
  • Plot VI curve for BJT with load line, show load line equation used.
  • Sketch (by hand, PSpice or any drawing program) the inverter with emitter resistor circuit.
  • Plot Vout vs. Vin curve (Transfer Characteristics curve) for Inverter, show constant region range (Vinmin-Voutmax,Voutmin-Voutmax) and gain computed from slope, explain the difference from the inverter result above.
  • Show Vinmidlle & Voutmidlle in constant region.
  • Show AC gain obtained from Oscilloscope readings, and VoutDC value, IoutDC equation and value.
  • Show Vin value to achieve Vout clipping, explain why clipping occurred at this value.

   

• Voltage Follower:
  • Plot VI curve for BJT with load line, show load line equation used.
  • Sketch (by hand, PSpice or any drawing program) the voltage follower circuit.
  • Plot Vout vs. Vin curve (Transfer Characteristics curve) for Inverter, show constant region range (Vinmin-Voutmax,Voutmin-Voutmax) and gain computed from slope, explain the difference from the two circuits results above.
  • Show Vinmidlle & Voutmidlle in constant region.
  • Show AC gain obtained from Oscilloscope readings, and VoutDC value, IoutDC equation and value.
