The disclosed embodiments comprise a multi-stage circuit operating across different power domains. The multi-stage circuit may be implemented as a master-slave flip-flop circuit integrated with a level shifter that transfers data across different power domains. The master and slave stages of the flip-flop may be split across two tiers of a 3D IC and may include (i) a level shifter across different power domain integrated within the flip-flop circuit, (ii) reduced one-state writing delays by a self-induced power collapsing technique, (iii) splitting flip-flop power supplies in different tiers using monolithic 3D IC technology, and (iv) cross power domain data transfer between 3D IC tiers. |
