Hi all ;

I want to plot a caracteristic of input current noise for an amplifier ( Schematic) in VIRTUSO 6.1.5 (CADENCE). there is someone know how to make it please

best regards ;
 

To obtain input noise characteristic You should divide output noise spectrum by transfer function of your circuit. I have not access to virtuoso now, but maybe it could be possible by running noise and ac analysis together (in the same frequency range) and try to plot it using formulea like:
Code: 
VN("/out_node")/VF("/out_node")
With accuracy to square/square root.

I could check it tommorow.
