Overview: This paper proposes a phase-locked loop (PLL) with dual PFDs and a modified Loop filter in which advantages of both PFDs can be combined and the trade-of between acquisition behavior and locked behavior can be achieved. By operating the appropriate PFD connected to the well-adjusted charge pump and regulating the loop bandwidth to input frequency ratio with an input divider and a modified loop filter, an unlimited error detection range, a high frequency operation, a reduced dead zone and a higher speed lock-up time can be achieved.
