Abstract
In this paper, a novel phase locked loop has been proposed using an analog band-selection loop. When the PLL is out-lock, the PLL has a fasting locking characteristic with the analog band-selection loop. When the PLL is near in-lock, the bandwidth becomes narrow with the fine loop. A frequency voltage converter is introduced to improve a stability and a phase noise performance. The proposed PLL has been designed based on a 1.8V $0.18{\mu}m$ CMOS process and proved by HSPICE simulation.
