摘要

Low power level shifter latch circuits with gated feedback for high speed integrated circuits, and a design structure on which the subject circuit resides are provided. A latch input stage operating in a domain of a first voltage supply receives a data input responsive to being enabled by predefined clock signals. A latch storage element coupled to the latch input stage includes a latch output stage operating in a domain of a second voltage supply provides a data output having a voltage level corresponding to the second voltage supply. The latch storage element includes a level shifting device providing level shifting from the first supply level to the second voltage supply level. The latch storage element includes feedback gate devices receiving the predefined clock signals to gate feedback to the latch input stage when data is being written to the latch input stage.
