Fully integrated frequency generator

Embodiments of the present invention include a frequency generator comprising a feedback loop with a transmission line integrated on a single integrated circuit. In one embodiment, a frequency generator comprises a phase detector and a voltage controlled oscillator coupled in series, and a transmission line having an input coupled to an output of the voltage controlled oscillator, the transmission line providing a time delay between the transmission line input and output, wherein the phase detector includes an input coupled to the transmission line output and another input coupled to the transmission line input. The phase detector, voltage controlled oscillator and transmission line are advantageously integrated on a single integrated circuit.
