This paper deals with new MTCMOS flip-flop architectures with high speed performance in active mode and ultra-low power dissipation in sleep mode. The use of new ultra-low leakage latch structure allows us to memorize the flip-flop state even during sleep mode and to strongly reduce the leakage in comparison with previous solutions.
