A 15-25 GHz RF Photonic Front-End with 22nm CMOS Dual-Differential Driver and Silicon Traveling-Wave Mach-Zehnder Modulator

A RF photonic front-end using dual-differential driving scheme is reported with a 22 nm CMOS FD-SOI driver co-integrated with a silicon traveling-wave Mach-Zehnder modulator. The proposed front-end achieves $15-25 \mathrm{GHz}$ bandwidth with 2 dBm IIP3 and consumes 448 mW.
