Abstract
Proposed is a device for receiving a four-level pulse amplitude modulation (PAM-4) signal, which includes a first comparator for comparing a received PAM-4 signal with a predetermined threshold voltage to output a most significant bit (MSB) signal; and a second comparator for comparing the differential signal difference between the positive signal and negative signal of the received PAM-4 signal with a reference voltage to output a least significant bit (LSB) signal.
