Abstract
This paper presents monolithic integrated InAlN/GaN NAND and NOR logic cells comprising depletion-mode, enhancement-mode and dual-gate enhancement-mode high electron mobility transistors (HEMTs). The designed NAND and NOR logic cells consist of the depletion-mode and enhancement-mode HEMT transistors integrated onto a single die. InAlN/GaN-based NAND and NOR logic cells with good static and dynamic performance are demonstrated for the first time. Calibrated static and dynamic electrophysical models are proposed for 2D device simulations in Sentaurus Device environment. Sentaurus Device mixed-mode setup interconnects the transistors to NAND and NOR logic circuits which allows analysis and characterization of the devices as a complex system. Circuit models of depletion-mode, enhancement-mode and dual-gate HEMTs are designed and calibrated by experimental results and 2D device simulations. The proposed models exhibit highly accurate results.
