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