AM Modulation with Current as Source

Hi,

 

I have created a circuit for Amplitude Modulation with ISIN as my source, when I simulate the circuit with VSIN as source I am able to simulate it but when I use current as source it says 

"Node is floating" 

 

Regards

Hi,

You should use a parallel resistor (with a low value) with your current source.

Could you send the image of your circuit?

Hi,

 

http://www.pspice.com/resources/application-notes/analog-behavioral-mode... (Figure 7)

 

This is the circuit, i have used "current" as my source.

Hi,

I have replaced the VSIN with the ISIN source, I have placed a parallel resistor and it works at my end free of errors. I do not understand, why it does not work at your end. Could you send please the image of your mdofied circuit?

Hi,

As I told you, please place parallel resistors:

Hi,

I cannot simulate project you sent me, because altough you sent me the lib file for the component you are using, there are components inside of it that are not defined. Have you sent me all the libraries?
