英文摘要: For wide band gap semiconductor heterostructures of noise and noise model of the mechanism of the status quo, the project team in the mechanism of GaN HEMT noise model based on the. Studied the GaN HEMT device noise sources, different width and different gate bias of the noise characteristics of GaN HEMTs, GaN HEMTs device structure of the device noise characteristics, etc. Three-year study period in the program carried out smoothly according to plan, completed the AlGaN / GaN heterostructure 2DEG simulation, proposed source parasitic impedance model, and an analysis of the model for GaN HEMT high-frequency noise. The initial establishment of the AlGaN / GaN HEMTs noise characteristics of the SVR model and equivalent circuit model. Proposed a new type of InGaN-based GaN HEMT device structure, and properties for the simulation. With the China Electronics Technology Group 55, completed the design of GaN HEMT, processing, testing, and use established equivalent circuit model. Designed a low noise amplifier module, completed validation of the model. Published 24 papers related to this project.
