A THz Signal Source with Integrated Antenna for Non-Destructive Testing in 28nm bulk CMOS KU Leuven
This work presents two fully integrated above-fmax signal sources (570GHz and 600GHz) with on-chip antenna, implemented in a 28nm bulk CMOS technology. A VCO generates a signal at the fundamental frequency, which drives a non- linear amplifier to generate the wanted third harmonic above. The above-fmax third harmonic signal is coupled directly to a folded dipole antenna (570GHz, -34.3dBm EIRP) or to a collinear dipole antenna through a ...
