Abstract
Official abstract text for this publication.
A voltage controlled oscillator (VCO) with low phase noise and a sharp output spectrum is desirable. The present disclosure provides embodiments of LC tank VCOs that generate output signals with less phase noise compared with conventional LC tank VCOs, while at the same time limiting additional cost, size, and/or power. The embodiments of the present disclosure can be used, for example, in wired or wireless communication systems that require low-phase noise oscillator signals for performing up-conversion and/or down-conversion.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-band, multi-injection voltage controlled oscillator (VCO), for providing a low phase noise oscillating signal at an output, the multi-band, multi-injection VCO comprising: a first cluster of inductor-capacitor tank VCOs configured to generate a first oscillating signal at a first frequency by magnetically coupling output oscillating signals generated by a first number of the inductor-capacitor tank VCOs in the first cluster to the output using a firs…
