  • Abstract
    A new architecture for a multi-band voltage-controlled oscillator (VCO) phase-locked loop (PLL) is presented, which can continuously maintain the optimum VCO sub-band and the VCO control voltage even with severe supply voltage variation. A prototype 2 GHz PLL with the new architecture is successfully demonstrated in 0.13 μm CMOS technology.
