Linear Large-Swing Push–Pull SiGe BiCMOS Drivers for Silicon Photonics Modulators

The analysis, design, and experimental characterization of a novel class of large-swing low output-impedance push-pull SiGe BiCMOS drivers are discussed. The circuits, which employ singleand series-stacked emitter follower (EF) and MOS-HBT cascode topologies, are intended to drive optical modulators with high-order m-pulse-amplitude modulated (PAM) signals, while maximizing energy/bit efficiency. ...
