A Segmented Mach-Zehnder Modulators Driver in 0.13 µm SiGe BiCMOS with an Output Swing of 3 Vppd at 25 Gb/s

In this paper, a segmented Mach-Zehnder Modulators driver using 0.13 μm SiGe:C BiCMOS is demonstrated. The capacitive negative feedback is implemented within the input stage, and inductive peaking and negative capacitance are adopted within each driver segment to broaden the bandwidth. A propagation delay between the output of two driver segments is created by microstrip transmission lines. The simulation results indicate that a differential output swing and a propagation delay are approximately 3 Vppd and 4.3 ps at 25 Gb/s, respectively.
