Various embodiments provide apparatuses, systems, and methods for resonant rotary clocking to generate synchronized clock signals. A base die may include a resonant ring structure to form a plurality of rotary traveling wave oscillators (RTWOs) coupled to one another in a rotary oscillator array (ROA). The ROA may provide synchronized clock signals at deterministic phase points that are tapped from the resonant ring structure. Multiple dies may be coupled to the base die (e.g., in a multi-die system) and may receive the tapped clock signals. Other embodiments may be described and claimed.

Techniques, circuits, and systems related to a multicore rotary traveling wave oscillator (RTWO) are provided. The multicore RTWO includes at least two metal layers and multiple RTWO cores, such that each core comprises a set of differential signal conductors that are interleaved across the metal layers to optimize space and reduce parasitic effects. The relative positional configuration of these differential signal conductors varies across a range of directionalities and/or orientations. In embodiments, an oscillator output signal is generated by the multicore RTWO; the frequency of this oscillator output signal is adjusted based on a comparison of its phase with that of a reference signal, such as within a phase locked loop circuit.
