Original Question: AD8338 in PSPice by Dave-Leyland
Unfortunately, I cannot put AdiSimPE on my PC as it is controlled by our central IT dept.
I have Cadence PSpice but I get errors trying to simulate AD8338:-
X_U1.BGAIN X_U1.VGAINOUT 0 X_U1.V X_U1.10** V
--------------------------------------------$
ERROR(ORPSIM-16147): Invalid parameter
+ GAIN -0.1 *4 *V VSUM
X_U1.BSLEW X_U1.VSLEW 0 X_U1.I X_U1.-1 *LIMIT
---------------------------------------$
ERROR(ORPSIM-16147): Invalid parameter
+ V VGAINOUT -V VSLEW 0.002 -0.002
X_U1.BCLAMP X_U1.VLIMIT 0 X_U1.V X_U1.LIMIT V
--------------------------------------------$
ERROR(ORPSIM-16147): Invalid parameter
+ VPRE 1.55 -1.55
X_U1.BMEAS VCC 0 X_U1.I X_U1.V GAIN
-------------------------------$

Can anyone help?
thanks

Thanks Jino, it worked a treat. I am a Spice newbie so I can't see how it models noise performance (if it does). What does .MODEL DGeneric D Is=1e-15 do?
Thanks
Dave

Hi Dave,
Apologies for late response.
.model DGeneric D Is=1e-15 corresponds to the diode model used in the circuit file, in AD8338.cir it wasn't use. Maybe it was left out in previous revisions. Will remove this on the next update.
Regards.
