Today's device is about minimizing volume
Active EMI Filter (AEF):
Active EMI filters inject a cancellation voltage or current to reduce radiated and conducted noise… actively. They can be built and tuned do-it-yourself style with op-amps, but it is always convenient to have a ready to place part, like this offering from Vicor. The volume and area savings come in because the inductor values needed for AEF are substantially smaller than passive EMI solutions.
