Looking for ideal fully differential amplifier spice model for XSPICE simulations. The one I have based on the XSPICE "gain" code model doesn't have any CMRR or care if outputs are swapped. Anything based on dependent sources would be good.

 

* XSPICE Fully Differential OpAmp
.subckt opamp inp inn outp outn in_offset=0 gain=300e3 out_offset=0
aint %vd(inp inn) %vd(outp outn) amp
.model amp gain (in_offset='in_offset' gain='gain' out_offset='out_offset')
.ends opamp
