Abstract :
A novel on-chip linear voltage regulator (VR), for use as PLL power supply is described. This voltage regulator exhibits a Power Supply Rejection Ratio (PSRR) of > 40dB and low thermal noise. Accurate current control enables optimized power and performance. These properties enable the VR to be utilized in PLL´s without adding any deterministic and random jitter. The VR has been designed and characterized in Intel´s recent leading-edge purely digital process.
