摘要

In this article, we present the modelling, design and characterization of a 3-Vppd linear-output-swing 90-GBd PAM-4 modulator driver, realised in III-V Lab's in-house 0.5-μm InP DHBT technology (380/520-GHz ${f_{T}/f_{{\max}}}$, 4.2-V ${BV_{\text{CE0}}}$). The driver exhibits 13-dB equalisation capabilities at 95 GHz with a bandwidth well beyond 110 GHz. It features a 0.67-W ...
