Abstract
An improved Phase Locked Loop (PLL) for digital integrated circuits. A characteristic of this PLL is that the Voltage Controlled Oscillator (VCO) output is fed to the phase and frequency detector (PFD) input through a clock-tree replica providing a delay equal to the routed clock tree. 'This enables the PLL to maintain the proper phase even during a sleep mode of operation.'
