DISTRIBUTED MACH-ZEHNDER MODULATOR (MZM) DRIVER DELAY COMPENSATION

Title:

DISTRIBUTED MACH-ZEHNDER MODULATOR (MZM) DRIVER DELAY COMPENSATION

Document Type and Number:

WIPO Patent Application WO/2016/188311

Kind Code:

A1

Abstract:

An electronic driver circuit for use with a modulator such as a segmented Mach-Zehnder Modulator (MZM) is provided. The electronic driver circuit includes a first delay buffer implemented as a first complementary metal-oxide-semiconductor (CMOS) inverter and a second delay buffer implemented as a second CMOS inverter. The second CMOS inverter follows the first CMOS inverter and has a second gate width smaller than a first gate width of the first CMOS inverter. The first CMOS inverter is configured to produce a first delayed electrical signal from a received electrical signal and the second CMOS inverter is configured to produce a second delayed electrical signal from the first delayed electrical signal produced by the first CMOS inverter.
