In the realm of VLSI circuits, addition and multiplication are the most pivotal operators in arithmetic units. In this regard, this work aims to propose an energy efficient 4:2 precise compressor utilizing 10 nm wrap gate CNTFET technology. The proposed compressor is constructed from 2 hybrids 14-transistors full adders. The proposed Gate All Around (GAA) CNTFET based full adder employs a hybrid XOR/XNOR logic structure to lower the transistor count and power consumption. After performing rigorous simulations, we have demonstrated that the proposed GAA CNTFET based full adder and 4:2 compressor depict 175.3 nW and 308.5 nW power consumption respectively along with superior propagation delay response (4.4 ps and 10.57 ps respectively) at a 0.5 V nominal supply voltage. Moreover, the proposed designs occupy a lower layout area (0.195 μm² and 0.43 μm² for the proposed full adder and 4:2 compressor respectively) compared to the other counterparts. Our results accentuate the application of the proposed GAA CNTFET based 4:2 precise compressor for ultra miniature microprocessing systems.

在VLSI电路领域，加法和乘法是算术单元中最关键的运算符。在这方面，这项工作旨在提出一种利用10 nm绕栅CNTFET技术的高效节能4：2精密压缩机。拟议的压缩机由2个混合式14晶体管全加器构成。拟议中的基于全环门（GAA）CNTFET的全加器采用了混合XOR / XNOR逻辑结构，以降低晶体管数量和功耗。经过严格的仿真后，我们证明了基于GAA CNTFET的全加法器和4：2压缩器在0.5 V标称电源下分别具有175.3 nW和308.5 nW的功耗以及出色的传播延迟响应（分别为4.4 ps和10.57 ps）。电压。此外，建议的设计占用的布局面积较小（0.195μm²和0.43微米²所提出的全加器和4：2压缩器分别地）相对于其他的对应。我们的结果强调了基于GAA CNTFET的4：2精密压缩机在超微型微处理系统中的应用。
