Abstract :
Summary form only given. A one-chip DC-DC converter IC with an on-chip planar inductor was developed. The planar inductor was placed on the LSI module with BiCMOS control circuitry and power MOSFETs. Therefore it is important to investigate the local EMI effect of the leakage magnetic field from the on-chip planar inductor on the lower LSI circuit. In this study, the local EMI problem in the monolithic DC-DC converter is discussed on the basis of a simulation of the magnetic field distribution.
