US 2026/0039518 A1 · MULTI-LEVEL PULSE AMPLITUDE MODULATION RECEIVING DEVICE AND ALL TRANSITION PHASE DETECTOR THEREOF

Abstract

A multi-level pulse amplitude modulation (PAM) signal receiving device comprises an all transition phase detector (ATPD) for receiving a data signal. The ATPD comprises a first-layer comparator structure to compare the data signal with critical voltages of the first-layer comparator structure to generate an error information, and a second-layer comparator structure connected to the first-layer comparator structure in series to compare reset speeds of the first-layer comparator structure to generate a data information. A decoder coupled to the ATPD for decoding the data information to generate a binary code. A least mean square engine coupled to the ATPD for updating the critical voltages based on the error information.
