HI...

I m doing my Mtech thesis on designing of univesal biquad filter using CFOA (current feedback op amp) in pspice simulation tool. So can anyone tell me how can i write syntax for CFOA in input file

You need to model Operational amplifier as sub circuit block in PSpice. You can also find the spice model from TI or ADI web sites. You may want to refer the following article **broken link removed**, this has explained modeling CFOA in detail. Another good reference on this topic is https://www.ti.com/lit/an/snoa368b/snoa368b.pdf

hope this helps.
