Inverse Alexander phase detector
Copyright policy )Inverse Alexander phase detector
An improved bang‐bang phase detector (PD) for multi Gb/s clock and data recovery (CDR) circuits is presented. The proposed PD is based on inverting the Alexander PD. In a typical subsampled CDR circuit, this Inverse Alexander PD results in a ten times better bit error rate (BER) compared with the conventional Alexander PD. Additionally, in the case of duty‐cycle distorted input data, this Inverse Alexander PD can even reach 20 times better BER compared with the conventional Alexander PD.
