摘要
摘要:通过分析差分传输管预充电逻辑(DP²L)的电路结构，发现该电路还无法达到完全的功耗恒定特性，仍然存在被功耗攻击的风险。针对该问题，该文对DP²L的电路结构进行改进，并用Hspice对改进前后的电路进行模拟仿真测试。实验表明：改进后的DP²L电路结构具有更好的功耗恒定特性，更能满足该逻辑电路的设计要求。

Abstract:By analyzing the circuit structure of Differential Pass-transistor Precharge Logic (DP²L), it is found that the circuit can not achieve the complete constant power consumption, and there is still a risk of being attacked by power attack. To solve this problem, the circuit structure of DP²L is improved by this paper, and the circuits before and after the improvement are simulated using Hspice. The experimental results show that the improved DP²L circuit structure has better characteristics of constant power consumption and can better meet the design requirements of the logic circuit.
