Zener diode Forward Bias Circuit

Zener diode Forward Bias Circuit Output Waveform


Simulation Procedure:
1. Open MULTISIM software.
2. Design1 – Multisim file will be opened. Save it as VI characteristics of Zener diode.
3. Select D1 5V zener diode from the real components list and place it in the working area.
4. Select Resistance, DC power source and ground from the same list and make connections as in the circuit.
5. Set the value of power source to 12V, and resistance as 220 ohms.
6. As seen in the above characteristics, the range of voltage is to be set at 0 – 1 V in steps of 0.1V. For this, select Simulate => Analyses => DC sweep.
7. In the DC Sweep Analysis, select Analysis Parameters. Set the start value as 0, stop value as 7 and increment as 0.5
8. After that specify the output variables. Select Output tab. Select the current across (IR1)resistance and click Add. Click Ok.
9. To Simulate the circuit, select Simulate => Analyses => DC sweep and click simulate.
10. The VI characteristics of Zener diode is displayed. In the grapher view as below, to change the labels of left axis and right axis, double click on it and change the labels as required.
