Resonant rotary clocking for synchronized clock signals

A multi-die system comprising:

• a base die that includes resonant rings of respective rotary traveling wave oscillators (RTWOs), wherein the resonant rings of different RTWOs are shorted to one another at respective shorting locations to form a rotary oscillator array (ROA);
• pass gates to selectively short respective pairs of the resonant rings to one another;
• one or more enable circuits, wherein individual enable circuits are to control respective sets of one or more of the pass gates;
• and
• a first die and a second die coupled to the base die, wherein the first and second dies are to tap respective clock signals from the resonant rings at respective tap points.
