Multi-band VCO PLL with continuously maintained optimum VCO control voltage

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 successfull...

Zusammenfassung:	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.
