Circuit Diagram

Procedure

1. Draw the circuit diagram after loading components from library. Assign net names for connections wherever necessary. Preprocess the circuit by invoking Simulation → Preprocess. Place waveform markers on input and output nodes.
2. For placing waveform markers, select Tools → Instruments → set wave form Contents → Voltage waveform →  Click on the required net and place the waveform marker. Run transient analysis after setting up required parameters.

 

3. To proceed with the simulation, the steps are as follows

Select ToolsComponentsComponent properties Change simulation parameters→ Click on the required component and change its values.

The values to be provided to the components are

Transistor        : BC107A (Click on the Set up Model of the Model Type. Click on Accept to get the default values assigned)

Zener diode     : Breakdown Voltage = 10V

Resistors         : 1k (1), 1.5k (1)

VDC/1             : 15V

 

4. For setting up simulation time and analysis types, select Simulation menu, choose Analysis. In the window pops up, select Transient analysis from tree view.

Enter following values:

Step                 : 1ยต

Final time         : 10m

Results             : Select Waveform from drop down menu.

 

5. Click on Accept. Expand the Transient Analysis and select Waveform viewer, Select As Marked. Click on Accept. Select Transient Analysis. Run Analysis by clicking on Run button.

 

6. For setting up DC Transfer function Analysis, select Simulation menu, choose Analysis. In the window pops up, select DC Transfer function analysis from tree view.

Enter following values:

First Source                 : VDC/1 [V5]

Start Voltage               : 0V

Stop Voltage                : 15V

Step                            : 500m

Results                        : Select waveform from drop down menu.

7. Click on Accept. Expand the transient tree view and select waveform viewer, click on As marked.  Click on Accept. Run Analysis by clicking on Run button
