Abstract

In this work, dual-gate enhancement-mode (E-mode) device based NAND circuit (DG-NAND) and the NAND block with double E-mode devices (DD-NAND) are developed and fabricated based on the GaN MIS-HEMTs (metal-insulator-semiconductor-high-electron-mobility-transistors) platform. The DG-NAND circuit has an area of 0.118 mm2 with the probe pad, which is 24% lower than the area of the DD-NAND circuit. Both static and dynamic experimental results validate the advantages of performance improvement of NAND circuits designed by dual-gate technology at an input voltage of 9 V. This paper demonstrates the design potential of dual-gate NAND in an all-GaN MIS-HEMTs platform through compact design.
