Fractional Rate Phase Detectors for CDR

godcadence

IEEE paper
Abstract—Some recent PLL designs utilize a half-rate phase
detector so that the VCO operates at a frequency that is one-half
of the input data rate. In this paper, a technique is proposed to
extend the half-rate phase detector structure to a rate of
 ,
for integer 
         
. The concept is explained using a rate 1/8
implementation and simulation results are presented to verify the
scheme. These rate
 phase detectors can be used to raise the
maximum operating frequency of clock and data recovery circuits
in a given CMOS process technology.
