Auto-tracking Method with Optimal Reference Voltage for PAM-4 Receiver
2021 18th International SoC Design Conference (ISOCC)（2021）
Abstract
This paper presents an auto-tracking method with an optimal reference voltage for a PAM-4 receiver. The auto-tracking optimal reference voltage circuit includes a center detector and a counter circuit that automatically finds optimal reference voltage directions in additions, three samplers, and a phase interpolator (PI) used in the existing normal operation of PAM-4. The key feature of the propos...
