  • Publication number: 20080219293
    Abstract: A method for transmitting signals along an interconnect in a VLSI system comprising receivers is disclosed. The VLSI based systems operate in the high Giga hertz range. The signals are transmitted along the interconnect as a localized wave packet i.e. as a pulse. The interconnect may be either electrically linear or nonlinear in nature.

  • Patent number: 7304555
    Abstract: To facilitate high frequency operation, transmission lines for high-speed interconnect applications in CMOS technologies are loaded with patterned permalloy or other ferromagnetic material films. Patterning the permalloy films as a plurality of segments results in control of the domain structures in the permalloy segments such that ferromagnetic resonance (FMR) effects are eliminated and eddy-current effects are reduced, thereby allowing operation of the transmission lines at frequencies of 20 GHz or higher. In addition, the patterned permalloy reduces the magnetic field coupling between two adjacent transmission lines. A novel ferromagnetic thin film characterization method is also employed to measure the microwave permeability of the patterned permalloy films and verify their high frequency operational characteristics.

  • Publication number: 20060205920
    Abstract: The invention relates to novel phosphorus-containing dendrimers having a core, at least one generation and an external layer consisting, completely or partly, of identical or different units, the said units satisfying the following formula (I): in which R1 and R2, which may be identical or different, are alkyl, alkoxy or aryl groups. These dendrimers are used for extracting actinides and lanthanides from aqueous solutions containing them.
