Is there any ISO 11452-4 compliant input filter?
At the moment, I have used a 22nF capacitor followed by 3.1uH ferrite bead for a linear current regulator. The load current is 1.2 A.
The linear current regulator has a low side MOSFET with an op amp which takes the feedback from the current set resistor.
The load current goes to zero at 200 MHz during the BCI test of 1 - 400 MHz.
Please suggest a solution? Do I need to change the value of the input capacitor or add few more capacitors?
Thanks.
