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 Ω 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.
