Abstract :
This paper presents a quarter-phase 32GHz PLL using 0.13um SiGe BiCMOS technology for a high speed microprocessor. The PLL characterizes a 3-state phase frequency detector (PFD), a charge pump loop filter, a VCO, a frequency doubler and a feedback 1/32 frequency divider. The VCO used in this PLL is a four -- stage ring oscillator that has a wide tuning range with a feed-forward interpolation topology for coarse frequency tuning and varactor diodes load capacitance variation for fine frequency tuning. The PLL has a wide locking range from 24.4 GHz to 39 GHz with a phase noise of-102dBc/Hz at 1MHz offset.
