A high-speed multi-phase oscillator based on self-timed ring is proposed. Self-Timed Rings
(STR) are promising approach for designing high-speed serial links and clock generators.
The architecture of STR allows us to achieve a maximum frequency with a multiphase
outputs since the oscillation frequency is not only depending on the number of stages but on
the number of “tokens” and “bubbles” circulating in the ring. In this paper, we propose a
method to design STR able to generate high-speed multi-phase outputs. All the electrical ...
