Hi guys,
I am trying to make a simple sensefet design for a buck converter, the problem is that my Vsen amplitude does not vary with respect to the inductor current of the buck.
I have used a Folded Cascode Amplifier (A=91dB BW=8Mhz phase=78) for the OpAmp. Is this enough to be used in the sensing circuit? Can anyone suggest on what may be the problem for my sensing circuit.
