Publication | 160-GSa/s-and-Beyond 108-GHz-Bandwidth Over-2-Vppd Output-Swing 0.5-μm InP DHBT 2:1 AMUX-Driver for Next-Generation Optical Communications

The publication “160-GSa/s-and-Beyond 108-GHz-Bandwidth Over-2-Vppd Output-Swing 0.5-μm InP DHBT 2:1 AMUX-Driver for Next-Generation Optical Communications” written by our partner III-V Lab has just been published on IEEE Xplore!

This publication reports on a 108-GHz bandwidth 0.5-µm InP DHBT analog-multiplexer-driver (AMUX-driver). To the best of the authors’ knowledge, this 2:1 AMUX-driver shows unprecedented 1.9-Vppd 160-GSa/s 160-GBd non-return-to-zero (NRZ) and 2.4-Vppd 100-GSa/s 100-GBd PAM-4 output swings, with very high-quality eye diagrams, without any digital signal processing (DSP) or postprocessing. Up to 3.2 Vppd is obtained in NRZ at 100 GBd. The lumped AMUX-driver also shows record 25.7-dB gain and 2.08-THz gain-bandwidth product with 11.1-dB equalizing capabilities at 86.6 GHz.

The authors are R. Hersent , A. Konczykowska , F. Jorge , F. Blache, V. Nodjiadjim , M. Riet, C. Mismer, and J. Renaudier.
