三独立栅场效应晶体管(TIGFET)是一种很有前途的下一代器件技术。它们的可换极性能力允许算术和顺序逻辑门的上级设计。在本文中,TIGFET技术已基准对几个超越CMOS器件。基准测试技术遵循了纳米电子研究倡议小组使用的类似方法。采用先进的15 nm工艺节点,研究了32位加法器和32位算术逻辑单元(ALU)的性能。TIGFET器件在32位加法器和32位ALU中的能量延迟积(EDP)与所有其他超CMOS器件相比都是最好的。特别地,TIGFET对于32位加法器和32位ALU分别具有比CMOS高性能(HP)低3.83倍和1.54倍的EDP。此外,与CMOS HP相比,TIGFET对于32位ALU具有相似的吞吐量。最后,由于TIGFET的超低漏电流和独特的电路设计,我们的结果表明,32位加法器的待机能量相比CMOS HP降低了两个数量级,与CMOS低电压相比降低了至少一个数量级。
Three-independent-gate field-effect transistors (TIGFETs) are a promising next-generation device technology. Their controllable-polarity capability allows for superior design of arithmetic and sequential logic gates. In this paper, the TIGFET technology has been benchmarked against several beyond-CMOS devices. The benchmarking techniques followed a similar approach used by the Nanoelectronic Research Initiative Group. The performance of the 32-bit adder and the 32-bit arithmetic logic unit (ALU) was investigated using the advanced 15-nm technology node. The TIGFET devices were shown to achieve the best energy-delay product (EDP) compared with all other beyond-CMOS devices for the 32-bit adder and competitive EDP for the 32-bit ALU. In particular, TIGFETs have 3.83 times and 1.54 times lower EDP than CMOS high-performance (HP) for the 32-bit adder and the 32-bit ALU, respectively. In addition, TIGFETs were shown to have a similar throughput for the 32-bit ALU compared with CMOS HP. Finally, due to TIGFETs’ ultralow leakage current and unique circuit designs, our results show that the standby energy of the 32-bit adder decreased by two orders of magnitude compared with CMOS HP and a decrease of at least one order of magnitude compared with CMOS low-voltage.
