EECE 315, Pre-Lab Report 03

Name

Date M/T/W/R/F

Collaborators

Pre-Lab Assume Vγ =0.6 V for all diodes, and assume the zener diode is ideal (rz = 0, Vγ.= 0.6 V).

1. Analyze circuits given in Fig. 1, Fig. 2, Fig. 3 (shown in next page). Explain and “EXPLICITLY STATE” ALL the status, assumptions, and applicable laws (theorems) that have been used in the analysis. Plot the input and output voltage waveforms.

a. Consider three different operating regions for diode(s) including “forward bias”, “reverse bias”, and “cut-off” region.

2. Use PSPICE to plot the input and output voltage waveforms of the circuits. Compare the results

with your experimental results in lab.
