Abstract
A 6.25 GHz PLL with an integrated LC-tank VCO designed and fabricated in 0.13 mum CMOS technology is described. For a deep submicron CMOS technology, leakage currents and limited voltage headroom degrade PLL performance. This paper introduces a new charge pump design with rail-to-rail operation and leakage cancellation techniques to overcome these constraints. Operated at 1 V supply voltage with an input reference clock frequency of 62.5 MHz, the PLL has 0.5 ps rms jitter at output frequency of 6.25 GHz
