Hi,
I am doing a common mode voltage AC analysis of a 2 stage OPAMP. When I plot the AC phase and magnitude, i get the following error.
Unable to plot expression <dB20((VF("/out") / VF("/in1")))>
because it does not evaluate to an object that can be plotted, like a waveform or
parametric wave. See the Visualization & Analysis Tool documentation for information
about the types of objects that can be plotted in Visualization & Analysis Tool. Only
the expressions that evaluate to those objects can be plotted.
*Warning* Wave11 is not a waveform object that can be displayed and
will be DELETED automatically.
name: "dB20(VF("/out")/VF("/in1"))"
I also get this error in red color in the beginning -
*Error* Evaluating expression (dB20((VF("/out") / VF("/in1"))))
*Error* ("eval" 0 t nil ("*Error* eval: unbound variable" gridResol))
But I am getting the phase plot and it is reasonably ok. How to overcome this error ? I click the output and the one of the inputs.
thanks in advance.
