We present a resonant clocking technique featuring rotary traveling wave oscillators (RTWOs) and a rotary oscillatory array (ROA) in Intel 4 CMOS for high-frequency, low-jitter, low-power and low-skew clock generation and distribution in 3D heterogeneous multi-die systems. The active base die incorporates an array of four coupled RTWOs capable of dynamic frequency tuning. Three independent resonant rotary rings are implemented to demonstrate the range of native resonant frequencies with very low jitter. The circuits operate across a wide frequency (3.2GHz-15GHz) and voltage (0.55V-1.2V) range with very low measured period jitter (107fs-705fs) and minimal duty-cycle distortion $(50\pm 0.8\%)$ suitable for multi-die high-performance GPUs.
