Energy efficient co-designed high-speed SiGe Driver for InP Mach-Zehnder modulator

This paper presents low-power and high-speed driver-IC developments for InP Mach-Zehnder modulator using a co-design technique. Two examples include an open-collector driver and 2-bit DAC using SiGe HBT technology. By exploiting the co-design technique, we can significantly reduce power consumption of the driver-IC and TOSA module. The open-collector and the 2-bit DAC consume 270 mW and 146 mW, respectively.
