摘　　要：Differential power analysis （DPA） poses a great threat to cipher security circuit since it exploits the dependency between the processed data and the power consumption. Two-phase Sense amplifier based logic （Two- phase SABL） suitable to DPA resistant logic style has been introduced under unbalanced load conditions. The pro- posed logic obtains constant energy consumption per clock cycle with pre-charge and evaluation phases. In this paper, Two-phase SABL cell and flip-flop are designed and simu- lated to confirm the energy balancing characteristic. Using TSMC 0.13μm CMOS technique, simulation results show that the power consumption fluctuations in the flip-flop is decreased by 15.1% under unbalanced condition and the area is reduced by 38.4%.
