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