    hi,

    i built this amplifier circuit but i do not know how to simulate it in multisim. Can anyone show me how to simulate this circuit in multisim?

    my requirement for this circuit is stage voltage of -100. If this circuit is not showing the gain of -100. what components should i change?

    sorry for my bad english but i hope you understand and thanks in advance.

    p/s: attached is the my circuit in multisim.

    Many people here don't like to open zip files. You might get more help if you posted a PNG of the schematic.

    I tried to unzip the file but its MS11 file type is not a valid one.
    I agree than a schematic should be attached as a normal PNG file type.

    How did you arrive at those odd component values?

    from my calculations, i assume it is correct.
    should I use standard values closes those i have in this circuit?

    That's the usual procedure since you can't readily buy arbitrary value components.

    Also, a gain of 100 is rather high for a single stage. Suggest you break it into two stages. That way each stage only needs a gain of 10.
