On-Chip Multi-Layer THz Power Generation with Beamforming Capability

In this article, we propose a novel on-chip multi-layer coupled oscillator scheme to generate THz power using industry standard 65-nm CMOS process. The scalable architecture enables to generate 14 dBm effective isotropic radiated power (EIRP) in a lensless setup with beamforming capability of ±30 degrees in both E and H planes at 416 GHz. The generated coherent power is radiated through on-chip 4×4 array of patch antennas.
