small signal TF from a file as a gain element in schematic.

vamshiky

Hi,

 I have a TF captured from an AC simulation in a file(gain,freq column data) 

Now I want this TF in schematic (like a gain element in the signal flow) so that it can filter off the noise in the circuit.

 

Thanks,

Vamshi

 

 

  • You could do this by doing an s-parameter analysis (sp) where you add port components from analogLib around the circuit, and then save (on the options form) a file of s-parameters. These could then be used on an instance of an nport from analogLib to represent the transfer functions (forward and reverse plus reflections) and information about how the impedances vary over frequency too.

    There's no support to do this with just some gain versus frequency arbitrary ASCII file (although that's to some extent what s-parameters contain).

    Regards,

    Andrew.
