I'm designing a circuit to process an signal from an Rogowski coil. As the voltage is the differential of the measured current, we have to integrate the voltage to provide a representation of current.
My question is; with the RC integrator, is it as simple as ramming a capacitor on in the feedback of a inverting amplifier? As the RC integrator naturally acts as a high pass filter, do I just select the gain resistors I need and then select the capacitors value depending on what the -3dB cut-off I want? What considerations need to be made to provide the best output signal possible?
