By using output control and MTCMOS techniques, we propose two low power low clock swing D flip-flops. Experimental results show that the leakage power of the proposed flip flops can be reduced more than an average of 59% in standby mode and in active mode the total power consumption can be reduced more than an average of 53% while the delay time stays the same. It is also show that the proposed D flip-flops can work even when the clock swing is nearly as low as V dd /3, though the delay time is much increased.
