Help with building an amplifier, new to multisim

[Dawnn]

Hi, I'm trying to build an amplifier circuit on Multisim. The schematic looks like this:

At the minute my multisim file looks like this:

The problem is that I can't seem to get an output. I'm relatively new to multisim and don't have a full understanding so I'm not sure where I'm going wrong. Is it a problem with replacating the actual circuit or is it a problem with how the instruments are connected?

Any help would be appreciated.

The input signal is grounded. That will do a really good job of making the output look very different from what you expect.

Hi Dawnn,

As I can see from what you are trying to build, you are missing a variable 100k resistor as far as the circuit is conserned and also it does look like you are trying to use differential measurements however, the grounds of the AI- and your signal don't seem to have the same ground.

I would highly recommend to start off with something simple by using only a couple components, see if you are getting what you would expect then move on and add more components.

Kind Regards,
