Abstract: This paper presents a D-band direct-digital transmitter that employs RF-DACs to perform modulation in the RF domain. It achieves 64-QAM with a maximum data rate of $48 \mathrm{~Gb} / \mathrm ...
Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Published in the journal Nature Communications, the ...
Abstract: This work presents an 135GHz direct-digital 16QAM modulator with independent amplitude and phase modulation. The modulator, implemented in 28nm CMOS, requires an 135 GHz local oscillator ...
