摘要:
This application relates to an active current compensation device which actively compensates for a noise occurring in a common mode in each of two or more high-current paths. In one aspect, the active current compensation device includes a sensing unit configured to generate an output signal corresponding to a common-mode noise current on each of the two or more high-current paths, and an amplification unit configured to amplify the output signal to generate an amplified current. The device may also include a compensation unit configured to generate a compensation current on the basis of the amplified current and allow the compensation current to flow to each of the two or more high-current paths, and a malfunction detection unit configured to detect a malfunction of the amplification unit. The malfunction detection unit and at least a portion of the amplification unit may be embedded in one integrated circuit (IC) chip.
