PSPICE-FOR-TI: Analog Behavior Model with current input

Hi JC,

Thanks.

For CCVS from this library the only parameter is GAIN, whereas I'm looking for mor complex source.

In the meantime I've found the EVALUE component from ABM library.

But it doesn't do what I expect - instead of Gaussian output (when running dc sweep) it gives strignt line.

It seems that exp function doesn't work.

In the shematic below - E1, E2 fail, E3 - Ok, but EXP output also fails.

Any comments ?

Sincerely,

Pavel.

Hi Pavel,

What is your DC sweep range?

Thanks,
JC

Hi JC,

0 ... 5u

Pavel,

Are you looking at all these waveforms on the same plot? If so, due to the limited sweep range, it could be possible that the variation is too small to show on the Y-axis due to the bias point.

You can try creating additional plots and each containing one individual trace to see if they are still flat. Or you can try running the simulation with increased sweep range.

Thanks,
JC
