  • Variable inductance circuitry for frequency control of a voltage countrolled oscillator
    Patent number: 8115557
    Abstract: An electronic device is made from a first substrate with device circuitry including an inductor and a second substrate with inductance adjustment circuitry including a number of other inductors. The substrates are assembled together to be opposite one another. The other inductors are arranged to provide a selection of different mutual inductance relationships relative to the inductor. These relationships are selectable during operation of the device to provide a variable inductance in the device circuitry.
