摘要： Two rings of a voltage controlled oscillator (VCO) configured to generate a plurality of phases of an oscillator signal, each ring of the two rings comprising three stages of inverters configured to generate a subset of phases of the plurality of phases of the oscillator signal, cross coupled via each stage to a corresponding stage in an other ring of the two rings using inverters to inverse-phase lock the subsets of phases of the plurality of phases of the oscillator signal of the two rings, and configured to receive inputs at each stage from a previous stage in the ring and a feed-forward signal from a successive stage in the other ring of the two rings, and a tail current supply configured to supply the two rings of the VCO with a tail current, the tail current comprising a low-magnitude proportional component and a high-magnitude integral component.
