A 50-Gb/s Multicarrier Transmitter Using DAC-Based Polar Drivers in 22-nm FinFET 150 150

Abstract:

A digital-to-analog converter (DAC)-based polar transmitter (TX) is proposed for multicarrier signaling in wireline applications. The proposed TX achieves a 50-Gb/s total data rate with maximized spectral efficiency by using three parallel 5-GS/s DAC-based drivers and two orthogonal carriers of 5 and 10 GHz. The three DAC-based drivers operating …
