A 2×44Gb/s 110-GHz Wireless Transmitter with Direct Amplitude and Phase Modulation in 45-nm SOI CMOS

This paper investigates the maximum Baud rate and the scalability to the W-Band of the mm-wave IQ power-DAC transmitter architecture. A 45-nm SOI CMOS implementation achieves 44-Gbps BPSK and 88-Gbps BPSK+OOK modulation rates at 100-110 GHz with energy efficiency of 9.4 pJ/bit and output powers ranging from 8.6 to 11.7 dBm.
