Hello experts,

I am making ibis models of differential cell in which output part is
something like this

VOA
| 50ohm 50ohm |VOB
| -----/\/\/\----|-----/\/\/\-----|
|
_|__
-- 0.5V
|
_|
\ / gnd

In this VOA and VOB are output pads and commen mode voltage is 0.5V. If
I apply any suplly on any pad then some current flow throgh 50 ohm
resistence. I am not able to understand how I model this current so that
every simulater read it. If I don't model it then there is drift in IBIS
and spice result.

Can any one help me to find out some solution.

Regards
Akhilesh
