I have an Operational Amplifier in Multisim 14 but i don't know how can i measure the Gain of this circuit. Is there any automatic way to do this?

Operational Amplifier example in Multisim 14

  • \$\begingroup\$ 1) measuring is done on a bench, this is a simulator, you're simulating. 2) the + input of the opamp is floating, you must connect it somewhere. 3) what is gain ? It is the ratio between output amplitude and input amplitude. Determine those, divide and you have your gain. \$\endgroup\$ – Bimpelrekkie May 18 '17 at 13:31

You can measure gain with the following steps;

1- Click Simulate > Instruments > Measurement Probe

2- Place the probe on the wire between the voltage source and the resistor.

3- Click Simulate > Instruments > Preset Measurement Probes > Voltage with reference to probe

4- Select Probe1 as the reference

5- Place the probe on the output. Notice that the visible measurements includes gain.

  • \$\begingroup\$ Thanks a lot wooz! I followed your instructions but i need one more tip. In the link of the image below i have Vgain(dc) = -188k. Should i divide Vgain(dc) with V(dc) of probe 1 to find the actual gain? ibb.co/crEwfk \$\endgroup\$ – bala9 May 18 '17 at 15:15
  • \$\begingroup\$ I am sorry to be late. You can remove Vgain(dc) or V(dc) value from probe2. 1- Right click probe2 and select properties. 2- In parameters section you can turn off the parameters you don't want to appear. \$\endgroup\$ – user125318 May 24 '17 at 12:00
