Design of New Adiabatic Digital Comparator with Pre-Computational Function
具有预计算功能的新型绝热数值比较器设计

Through the study of the working principle and structure of Clocked Transmission Gate Adiabatic Logic (CTGAL) and digital comparator, a new design scheme of digital comparator which has the pre-computational function is proposed based on CTGAL. The scheme has the redundancy- restraining function, and it can attain energy saving of about 60% compared to the digital comparator based on PAL-2N. The PSPICE simulation results indicate that this digital comparator has correct logic function and the character of clearly low power.
