Navigating the Challenges of 300GHz CMOS Transceivers: A Comparative Analysis with Photonics-Based and D-Band CMOS Configurations

The realization of 300GHz transceivers presents a pivotal challenge in advancing high-data-rate wireless communication, especially as defined by the IEEE 802.15.3d standard. While photonic methods and D-band CMOS configurations have paved the way for THz communication, CMOS technology offers unique advantages, particularly in cost-effective mass-production and integration with consumer devices. This talk will compare the limitations and strengths of photonics-based 300GHz transceivers, D-band CMOS configurations, and the more recent 300GHz CMOS implementations. By addressing key challenges such as amplification, phased arrays, and power-efficient demodulation, we will demonstrate how CMOS technology is evolving to overcome the hurdles of THz communication, offering a viable path for widespread adoption in everyday consumer electronics.
