摘要

物联网(IoT)和便携式电子设备对提高生活水平至关重要,而电池效率和紧凑型设计对这些设备至关重要。模拟传感器是先进人工智能不可或缺的组成部分,通常需要复杂的实时处理和驱动。本研究探讨了一维扶手石墨烯纳米带在石墨烯纳米带场效应晶体管(GNRFET)中的性能。它将基于石墨烯纳米带的三重级联运算跨导放大器(GNRFET-TCOTA)与基于传统 CMOS 的 TCOTA 进行了比较。研究结果表明,基于 GNRFET 的 TCOTA 有了大幅提升:纯 GNR-TCOTA 变体的直流增益显著提高了 33.8%,而电导率、压摆率和增益带宽也有了显著改善,分别提高了 8.48 倍、5.85 倍和 8.56 倍。此外,与基于 Si-CMOS 的 TCOTA 相比,纯 GNRFET TCOTA 表现出更高的速度、更低的能延积和沉淀时间。研究还探讨了关键设计参数对电路性能的影响。总之,该研究强调了 GNRFET 在优化 TCOTA 电路方面的潜力,为实现更高效、更紧凑的电子设备提供了途径,从而推动了纳米电子学的发展,支持了高性能物联网系统的增长。

Graphene nanoribbon FET technology-based OTA for optimizing fast and energy-efficient electronics for IoT application: Next-generation circuit design

The Internet of Things (IoT) and portable electronic devices are pivotal in enhancing living standards, with battery efficiency and compact design being critical for these devices. Analogue sensors, integral to advanced artificial intelligence, often necessitate complex real-time processing and actuation. This study examines the performance of one-dimensional armchair graphene nanoribbons in graphene nanoribbon field-effect transistors (GNRFETs). It compares graphene nanoribbon-based triple cascode operational transconductance amplifiers (GNRFET-TCOTAs) with conventional CMOS-based TCOTA. The results reveal substantial enhancements in the GNRFET-based TCOTAs: the pure GNR-TCOTA variant shows a remarkable 33.8% increase in DC gain and significant improvements in transconductance, slew rate, and gain-bandwidth, with enhancements of 8.48, 5.85, and 8.56 times, respectively. Furthermore, the pure GNRFET TCOTA exhibits higher speed, lower energy-delay product, and settling time compared to Si-CMOS-based TCOTA. The study also investigates the impact of critical design parameters on circuit performance. Overall, the research highlights the potential of GNRFETs to optimize TCOTA circuits, offering a path towards more efficient and compact electronic devices, thereby advancing the state of nanoelectronics and supporting the growth of high-performance IoT systems.
