120Gbaud SiGe BiCMOS electronics for next-generation optical interconnects

Innovative transmitter IC architecture enables >80GHz analog output bandwidth

Summary

Scientists from IDLab, an imec research group at Ghent University, have demonstrated a 120Gbaud transmitter IC that implements a SiGe BiCMOS multiplexer, equalizer and driver. 

The innovative architecture enables a significant increase in baud rate combined with a high analog output bandwidth. The scalable SiGe BiCMOS technology can be implemented at high manufacturing volume, paving the way to cost-effective high-speed optical transceivers for the terabit era.

The 120Gbaud transmitter IC was presented at the 2021 IEEE Custom Integrated Circuit Conference (CICC).
