Three conference presentations in one week
Jaehong Jung presented his work on a 60-GHz CMOS fractional-N PLL at the IEEE VLSI Technology & Circuit Symposium in Kyoto, Japan (TSMC 28-nm, 58 fs rms jitter at 28 mW). Pradyot Yadav (co-advised by Prof. Tomás Palacios) presented a 3D mm-wave heterogeneous integration technology at IEEE RFIC in San Francisco. Mingran Jia (co-advised by Prof. Anantha Chandrakasan) presented a 260-GHz retro-backscatter THz ID chip at RFIC. Both Pradyot's and Mingran's papers were finalists for the Symposium's best student paper awards.
