“A 47-to-100GHz Oscillator-embedded Artificial Transmission Line based LO Generator Achieving Averaged FoMt of -193.7 dBc/Hz” (Best Student Paper Award Finalist)
A fully integrated mm-wave LO generator achieves continuous 47-100 GHz coverage (72.1% tuning range) using six switched oscillator-embedded transmission-line cells, each targeting a designated sub-band. Fabricated in 65-nm CMOS, the design delivers -112 to -118 dBc/Hz phase noise at 10 MHz offset and a best-case FoMt of -199.8 dBc/Hz.

“A Broadband 241-306 GHz Frequency Multiply-By-24 Based Coherent Radiator Delivering +26.5 dBm EIRP in 90-nm SiGe BiCMOS”
A fully integrated 300 GHz-band coherent radiator achieves a record 29.6% tuning range using a ×24 frequency multiply chain and on-chip dipole antenna. Fabricated in GlobalFoundries 90-nm SiGe BiCMOS, the prototype delivers a peak EIRP of +26.5 dBm at 267 GHz, 26.5 dBc harmonic rejection, and 1.2% DC-to-THz efficiency at 148 mW DC power.
