The N-over-N cascode push-pull modulator driver is demonstrated at 20 Gbit/s with IBM 130 nm technology. Electro-optical measurement of the modulator driver integrated with a Mach-Zehnder modulator (MZM) is also presented. This modulator driver achieves 50 Omega output impedance matching (for the MZM) with on-chip termination. The power consumption of the modulator driver is 312 mW and the output swing is 3.4 V-pp on the differential.
