Use the transistor model supplied in class. From the PSpice results determine the quantities listed below . Show your work, If you use printed output files to determine values, circle or highlight the specific values used. Determine and list the results from PSpice for: I D | Q , V GS | Q , and V DS | Q and g m the Q point values for the FET A vm (total) = V out /V sig in the midband f l , and f h the low and high frequency 3dB points (Note these values aren’t expected to be the exact same as in-class assignment estimates.) Include the following as part of your solution: a) Your circuit – the schematic . b) Do a detailed bias point analysis and turn in a

Unformatted text preview: copy of the output file (*.out) This should have the dc voltages and transistor Q point parameters. ECSE-2050 Spring 2007 Introduction to Electronics c) Do an AC frequency scan, use probe and turn in a Bode Plot of V out / V sig . Remember: a Bode Plot is actually 2 plots; one is the gain in db vs. frequency. The other is the phase shift vs. frequency. The frequency axis should use a log scale. There are db and phase functions in probe. Any calculations necessary to determine the quantities listed above, along with the results. d) Compare your results with the calculated theoretical values e) Attach with your simulation Results, the calculations for the above quantities (dc operating point, gain, low and high 3dB frequency)...
