An electronic apparatus and an electronic system may include a first power delivery network (PDN) and a second PDN. The first PDN may include a first inductor as a segment of a power rail of the first PDN, while the second PDN may include a second inductor as a segment of a power rail of the second PDN. The first inductor and the second inductor may form a magnetically coupled inductor. The magnetically coupled inductor may provide migrated impedance ZT to the first PDN induced by the magnetically coupled inductor. The migrated impedance ZT to the first PDN may help the first PDN to reduce its voltage noise. Other embodiments may be described and/or claimed.
