  • Differently-tuned VCO using inductively coupled varactors
    Patent number: 7061340
    Abstract: A differently-tuned voltage controlled oscillator (VCO) and its application in a multi-band VCO tuner are disclosed. In one aspect of the invention, the VCO comprises a plurality of serially connected inductive elements each including inductively coupled inductor elements, a varactor element connected in parallel with the serially connected first inductor elements and means to apply a first and second tuning voltage to elements of the varactor element. In a second aspect, the VCO further comprises a second varactor element connected in parallel with the inductive elements, and means to apply the second tuning voltage elements of the second varactor element.
    Type: Grant
