【Abstract】 To implement high speed phase-locked loops circuit,on the basis of analyzing the conventional phase/frequency detector of CMOS phase-locked loops,a fast phase/frequency detector is designed for the CMOS phase-locked loops to reduce the delay time.The circuit is designed by using the 0.13μm CMOS process and HSpice simulating results show that the designed fast phase/frequency detector can reduce half delay time.更多还原
