Abstract
In this work, a 270-GHz steerable oscillator array has been implemented using a 28-nm CMOS technology with phase control by gate bias tuning. Four unit oscillators, which adopted source degeneration with a push-push topology for 2nd harmonic generation, are coupled to form a 1×4 array, the radiation being achieved by on-chip patch antennas. The unit oscillator demonstrated a tuning range of 254 to 274 GHz with 10 mW of DC power dissipation at gate voltage 0.7 V. The fabricated 1×4 array exhibited a maximum EIRP of -6.4 dBm, with beam steering demonstrated with a proper combination of gate biases.
