Patent ID: 11888654
Assignee: NANYANG TECHNOLOGICAL UNIVERSITY
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 8:
9. A receiver comprising:
a differential signal generator configured to receive a single-ended Pulse Amplitude Modulation (PAM)-N signal, where N is an odd number, and generate differential signals based on the single-ended PAM-N signal, a reference signal, and a pair of compensation signals;
an offset detector circuit configured to detect a predetermined signal pattern from a digital signal determined based on the single-ended PAM-N signal, and generate an offset detection signal when a comparison result signal of a positive signal and a negative signal included in the differential signals in signal periods corresponding to the predetermined signal pattern matches a predetermined offset pattern; and
an offset compensator configured to adjust signal levels of the reference signal and the pair of compensation signals in response to the offset detection signal, and provide the reference signal and the pair of compensation signals having adjusted levels to the differential signal generator.
