A D-Band ASK Transmitter with 50GHz RF Bandwidth and Multi-Mode Interface Implemented in 28nm CMOS

As the demand for communication rates increases, the existing Sub-6GHz frequency band has become very crowded and difficult to meet future communication needs. The abundant spectrum resources of the millimeter-wave (mm-Wave) provide potential solutions to this problem, while terahertz (THz) has received increasing attention due to its significant absolute bandwidth advantage in recent years [1]–[3]. The D-band (110–170 GHz), which can provide abundant spectrum resources and is within the frequency range of high-performance devices designed using silicon-based processes, has become more and more attractive in recent years. Communication systems based on amplitude shift keying (ASK) modulation format are widely studied and applied in THz communication systems due to their simple structure.
