In this paper, a linear driver for optical modulators in a 0.13 μm SiGe:C BiCMOS technology with fT/fmax of 300/500 GHz is presented. The driver is implemented following a distributed amplifier topology in a differential manner. In a 50-Ω environment, the circuit delivers a maximum differential output amplitude of 4 Vpp, featuring a small-signal gain of 13 dB and 3-dB bandwidth of 90 GHz. Time-domain...
In this work, a monolithically integrated segmented driver and Mach-Zehnder modulator (MZM) in 0.25 µm SiGe:C BiCMOS technology is presented. The driver and the modulator are divided in 16 segments and the MZM has a total length of 6.08 mm. The driver has a maximum gain of 14.5 dB. Electro-optical time-domain measurements were performed and an optical eye-diagram with more than 13 dB of extinction...
In this paper a linear optical modulator driver fabricated in a 0.13 µm BiCMOS SiGe:C technology is presented. The prototype is to be used in hybrid configuration with an InP segmented Mach-Zehnder modulator (SE-MZM), forming a transmitter sub-system with direct interface to the digital to analog converter (DAC), which is suitable for high order modulation formats. A tunable broadband delay line that...
In this work, a modulator driver in 0.13 µm SiGe:C BiCMOS technology for 25 Ω travelling wave electrode (TWE) Mach-Zehnder Modulators (MZM) is presented. The design integrates two channels for differential driving of IQ signals. The driver delivers a differential output signal of 4 Vpp, exhibits a differential gain of 12 dB and has an output return loss better than 9 dB. It works from a 4.7 V supply...
