PhD Oral Preliminary Examination – Abhishek Agrawal

A Scalable 28GHz Coupled-PLL in 65nm CMOS with Single-Wire Synchronization for Large-Scale 5G mm-Wave Arrays
This research presents a scalable, single-wire synchronization architecture and circuits for mm-Wave arrays that preserve the simplicity of daisy-chained LO distribution, compensate for phase offset due to interconnect, and provide phase noise improvement with an increase number of PLLs. Measurements on a scalable 28GHz prototype demonstrate a 21% improvement in rms jitter and 3.4dB improvement in phase noise at a 10MHz offset when coupling 28GHz PLLs across three different ICs.
