Aim


To simulate an opamp precision half wave rectifier circuit.

Components Required


Opamp- 741 (1), Resistor-RC05 (3), Diode-1N4001 (2), AC voltage source - VGEN (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.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 parameter is to be assigned)
        Diode : 1N4001 (2) (Click on the Set up Model of the Model Type. Click on Accept to get the default values assigned)
        Resistors : 1.2k (3)
        VDC/1 : 15V
        VDC/2 : -15V: -15V
        VGEN : Select the source function as SIN and set its Properties as follows
                    VA (amplitude) : 100m
                    FREQ (frequency) : 1kHz   

Click Accept for values to get effected.

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 : 1µ
        Final time : 2.5m 
        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.
