Hi,
how do I simulate a bode plot of a current feedback amp (cfa)? The known testbench from the vfa doesn't work because of the feedback resistor.

Please, be more specific. What do you want ?
1) Just the pure CFA (without feedback)?
2.) Loop gain for CFA with feedback?
3.) Gain for CFA with closed feedback loop ?
 

hi,
I just want to simulate the bode plot for open loop and close loop. Closed loop means a specific feedback resistor and a special gain resistor.

OK, and what is the problem ? In both cases you can use the normal simulation setup from voltage opamps.
