Method and system for a voltage-controlled oscillator with a leaky wave antenna
View Patent ↗Methods and systems for a voltage-controlled oscillator (VCO) with a leaky wave antenna are disclosed and may include transmitting wireless signals via one or more leaky wave antennas in one or more tank circuits coupled to one or more VCOs. The VCOs may be two-point modulated. Two modulating signals may be communicated to the one or more VCOs via varactors coupled to tank circuits on the one or more VCOs. The varactors may include CMOS transistors with source and drain terminals shorted together. The one or more leaky wave antennas may be integrated on the chip, on a package to which the chip is affixed, or on a printed circuit board to which the chip is affixed. The VCOs may be integrated in a phase-locked loop and an output of the one or more VCOs in the phase-locked loop may be fed back via a multi-modulus detector.
