SQUARE WAVE GENERATOR


Download Square Wave Generator.epb

Aim

To simulate a Square wave generator.

Components required

OPAMP-741(1),Resistor - RC05 (3),Capacitor-CC0805(1), DC voltage source - VDC (2), Ground- SPL0 (4)

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 Tools → Components → Component properties→ Change simulation parameters→ Click on the required component and change its values.

The values to be provided to the components are

OPAMP          :741(Since it is a subcircuit,no parameters is to be assigned)

Resistors       :10k(2),20k(1)

Capacitors     :0.1µF

VDC/1            :15V

VDC/2            :-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                : 10µ

Final Time       : 5m

Max.Step         : 10µ

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.
