  • Circuit arrangement
    Patent number: 7411469
    Abstract: A circuit arrangement having a plurality of variable capacitance elements such as varactors is described, the varactors having associated electronic control means which controls the capacitance of the variable capacitance elements over a control range. The control range is such that for any particular variable capacitance element a complete variation from a lowest to a highest capacitance is obtained from only a portion of the control range.
    Type: Grant
    Filed: October 10, 2006
    Date of Patent: August 12, 2008
    Assignee: Intel Corporation
    Inventors: Colin Leslie Perry, Stephen John Parry, Alessandro F. Deidda, Christopher R. Shepherd
  • Variable capacitance circuit arrangement
    Patent number: 7358825
    Abstract: A variable capacitance network is disclosed, comprising a plurality of capacitance arms connected in parallel with each other between first and second terminals of the network. Each capacitance arm has a varactor and a series capacitor in series with the varactor A control input applies a common control signal to the junctions between the varactors and their associated series capacitors, to allow for simultaneous control of each varactor.
