Noise generator Multisim


Hello, I am student and new to Multisim software.

I'm trying to generate noise (thermal) across a current source. Can some one  please suggest me how to do it ?

I have found thermal noise genarator for voltage source . How can I use it across current source?


Any suggestion will be appreciated. Thank You.

Hi Shetty14,


use the Thermal Noise component: "Thermal noise source. Produces the white noise generated by a resistor due to thermal effects."


Place>>Componetnts>>Signal Voltage Sources>>Thermal Noise


Adding an appropriate series resistor to the model will result in a "noise current" of corresponding rms value.


This noise current you can add to another current by applying parallel connection.


Best Regards,
