  • ASSEMBLY, CHIP AND METHOD OF OPERATING
    Publication number: 20090146760
    Abstract: The chip (100) comprises a network of trench capacitors (102) and an inductor (114), wherein the trench capacitors (102) are coupled in parallel with a pattern of interconnects (113A,B, . . . ) that is designed so as to limit generation of eddy current induced by the inductor (114) in the interconnects (113A,B, . . . ). This allows the use of the chip (100) as a portion of a DC-DC converter, that is integrated in an assembly of a first chip and this—second chip (100). The inductor of this integrated DC-DC converter may be defined elsewhere within the assembly.
