1 Use PSpice (or alternate) to obtain the i-v characteristic of the diode with model number D1N4002 (very common one). Sweep the input voltage from -15 V to 15 V.

Construct the following schematic. Select the setup from the analysis menu, click the DC Sweep dialog button. The DC sweep dialog box appears. For the Sweep variable type select the voltage source, and set its name to Vss. Using the sweep type linear, set the starting value to -15, end value to 15 and increment to 0.1. When simulation is complete probe graphic window appears. Add the trace I(D1). You need to obtain the Diode l-V curve. Comment on your results
