Abstract:
A noise filter circuit for an IC is provided. The noise filter circuit comprises a decoupling unit coupled to a power pad of the IC and a current amplifier circuit coupled to the decoupling unit and the power pad of the IC. The decoupling unit generates a first current in response to a transient voltage being on the power pad of the IC. The current amplifier circuit drains a second current from the power pad of the IC according to the first current.
