Patent number: 7999713Abstract: The invention relates to fast, high resolution, analog digital converters, and more particularly those which possess at least one conversion stage of “flash” type. The converter according to the invention uses N differential amplifiers with four inputs. The amplifier of rank j receives the input voltage to be converted Vep?Ven on two first inputs, and a reference potential difference on two other inputs. The reference potential difference is obtained between two taps of networks of resistors that are identical operating in parallel and supplied between a high voltage source and a low current source; the taps for an amplifier are respectively a tap Pj of rank j of a first network and a tap P?N?j+1 of rank N?j+1 of a second network. This reduces the first and second order non-linearity effects due to the fact that the differential amplifiers consume an input current tapped off from the networks of resistors.Type: GrantFiled: March 13, 2008Date of Patent: August 16, 2011Assignee: E2V SemiconductorsInventors: Jean-Alain Nicolas, Richard Morisson

Patent number: 7998895Abstract: Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and ?-olefins, and the copolymerization of such olefins with polar group-containing olefins.
