Transfer function generation tool

[rela]

Dear experts,

I'm thinking if there are any free tools available for download which are capable of generating transfer functions based on a drawn amplifier circuit?

A SPICE package would do that. Have you looked at freeware/student SPICE packages?

Well, do you want... a numerically solved transfer function, i.e. a plot of the transfer function? Or do you want an s-domain mathematical expression?
