نویسنده
چکیده
There is several application of phase locked loop in the field of communication. It depends on the mixed signal operation. It is capable of fast locking capability. present work based on redesign of the PLL system using 90nm technology process at frequency 1 GHz and the lock time is 179.5 ns and transient analysis of the PLL is simulate between 1ns to 1000ns.it consumes the 179.5 mW power at 1.8V D.C. supply. VCO design which is used as main part of the PLL present design of PLL using Ring VCO design it consumes 1.409 watt power Keywords— PLL (Phase locked loop), PFD (phase frequency detector), VCO (voltage controlled oscillator), CP (charge pump).
