ABSTRACT:
Saturation of nonlinear ferromagnetic core material for on-chip inductors for high current applications is significantly reduced by providing a core design wherein magnetic flux does not form a closed loop, but rather splits into multiple sub-fluxes that are directed to cancel each other. The design enables high on-chip inductance for high current power applications.
