A 308-317GHz Source with 4.6mW Peak Radiated Power and on-Chip Frequency-Stabilization Feedback in 0.13µm BiCMOS

In this paper, a 308-317GHz radiating source is presented. The output frequency of the 6×4 radiator array is stabilized with an entirely on-chip frequency detection and feedback mechanism realized mainly by passive EM structures. This feedback mechanism eliminates the need for both frequency dividers and the off-chip reference, achieving much lower system cost and power consumption. Fabricated using a 0.13μm BiCMOS process, the proposed source achieves a peak radiated power and EIRP of 4.6mW and 24.7dBm, respectively, with a total de power consumption of 1.18W. The frequency tuning range is larger than 2.7%. The measured phase noise at IMHz offset is -80.1dBc/Hz.
