SUMMARY

The discussion centers on verifying the Shockley equation through a specific circuit outlined in a lab script from the University of Glasgow. The user seeks clarification on the operation of the circuit to prepare for a 5-minute oral presentation. Key components of the circuit include semiconductor devices, and understanding their behavior is essential for accurate results interpretation. The Shockley equation is fundamental in describing the current-voltage characteristics of diodes, making comprehension critical for successful presentation.

PREREQUISITES
  • Shockley equation fundamentals
  • Basic semiconductor physics
  • Circuit analysis techniques
  • Understanding of diode characteristics
NEXT STEPS
  • Study the Shockley equation and its applications in semiconductor devices
  • Learn about diode current-voltage characteristics and their graphical representation
  • Explore circuit analysis methods, including Kirchhoff's laws
  • Review the lab script provided by the University of Glasgow for detailed circuit schematics
USEFUL FOR

Physics students, electrical engineering students, and anyone preparing to present on semiconductor circuits and the Shockley equation.

For my 3rd year lab i need to verify the Shockley equation by building the circuit shown on page 4 of the link below:

http://www.physics.gla.ac.uk/Physics3/Lab%20scripts/semiconductors.pdf

Can anyone explain to me how this circuit works? thanks

No one know, coz I've got to give a 5 min oral presentation describing how this circuit works before explaining my results and i really don't know where to start
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
