Abstract: This letter presents a 248 GHz compact direct-conversion transmitter with IQ and LO feedthrough (LOFT) calibration capability, which can achieve a data rate of 20-Gb/s with 16-QAM. The ...
Abstract: This study presents a 112-Gb/s four-level pulse-amplitude modulation transmitter implemented in a 28-nm CMOS process. An innovative quasi-voltage-mode driver is proposed, which demonstrates ...
