PSPICE A/D simulation problem

[RsK]

Hi anyone can see the pspice file and please tell me how to remove the
error it displays while simulation?

Top posting to be as big an annoyance as possible ;-)

(1) You show a model of an NPN. But there is no NPN in the netlist.

(2) What does the error message say?

Hello rizwan,

I don't know what PSPICE reports, but the error report from
LTspice is crystal clear if you know SPICE.

WARNING: Node 1 is floating.
WARNING: Less than two connections to node 1. This node is used by C1.
---> one pin of C1 is not connected

No AC stimulus found:
Set the value of a current or voltage source to "AC 1."
to make it behave as a signal generator for AC analysis.
---> An AC-analysis requires at least one voltage source with an "AC"
definiton.


This doesn't matter, but why do you have a transistor model when you don't
use a transistor?

Best regards,
Helmut
