A 6-Gb/s PAM-3 transceiver with background time-varying offset sensing and compensation

Time-varying offset such as transistor aging increases mismatches of differential pairs at pulse amplitude modulation (PAM)-3 transceivers, exacerbating signal integrity. To tackle this issue, this letter proposes a time-varying offset sensing and compensation technique for a PAM-3 transceiver. The...
