摘要： A voltage-controlled oscillator (VCO) of ring-connected stages, where each stage in the VCO has a first set of differential inverters biased by variable bias voltages, and a second set of differential inverters biased by fixed bias voltages. The differential inverters in each stage are connected in parallel with each other. Each set of differential inverters in a stage may contain only one differential inverter. The variable bias voltages are provided by charge pumps and associated circuits as used in well-known self-biasing schemes for phase locked loops. The fixed bias voltages are provided by a biasing circuit, matched to the circuits associated with the charge pumps, but where a fixed control voltage is applied to provide the fixed bias voltages.

摘要： A system is provided that includes a power distribution network to provide a switching current and a resonance reduction circuit to sense the switching current within a frequency range and to generate a resonance reduction signal having a current component at substantially a same frequency and substantially 180 degrees out of phase from the sensed switching current. The power distribution network may combine the switching current with the resonance reduction signal to provide a total switching current that may be provided to a processor as the powering signal.
