Furthermore, complex modulation schemes such as PAM-4 have been introduced to improve the trade-off between circuit bandwidth, power consumption, data-rate and optical-link range compared to NRZ signaling. Therefore, the cost advantage of a fully integrated silicon solution will eventually push classical discrete implementations toward
