N-over-N cascode push–pull modulator driver in 130 nm CMOS enabling 20 Gbit/s optical interconnection with Mach-Zehnder modulator
PROJECT TITLE :
N-over-N cascode push–pull modulator driver in 130 nm CMOS enabling 20 Gbit/s optical interconnection with Mach-Zehnder modulator
ABSTRACT:
The N-over-N cascode push–pull modulator driver is demonstrated at twenty Gbit/s with IBM one hundred thirty nm technology. Electro-optical measurement of the modulator driver integrated with a Mach-Zehnder modulator (MZM) is additionally presented. This modulator driver achieves fifty Ω output impedance matching (for the MZM) with on-chip termination. The ability consumption of the modulator driver is 312 mW and therefore the output swing is 3.4 Vpp on the differential.
