Abstract

The invention discloses a GaN HEMT equivalent circuit topological structure based on a novel resistance model. The GaN HEMT equivalent circuit topological structure comprises a transistor GH, whereina grid G, a source S and a drain D of the GH are respectively connected with one ends of inductors L1, L3 and L2; the other end of the L1 is connected with one end of a capacitor C1, one end of a resistor R1 and one end of a capacitor C2; the other end of the resistor R1 is respectively connected with one end of a capacitor C3 and one end of a capacitor C4; the other end of the C3 is connected with one end of a resistor R2; the other end of the capacitor C4 is connected with one end of a resistor R3; the other end of the resistor R3 is respectively connected with one end of a current source Ids, a capacitor C5, a resistor R5 and one end of a resistor R4; and the other end of the resistor R2 is respectively connected with one end of the resistor RS, the other end of the current source Ids,the other end of the C5 and the other end of the R5. According to the GaN HEMT equivalent circuit topological structure, a novel parameter Rs model of the resistor RS is adopted, so a problem that theparameter Rs of the resistor RS changes along with the change of drain-source current and temperature can be solved.

Description

technical field [0001] The invention relates to the technical field of semiconductor device modeling, in particular to a GaN HEMT equivalent circuit topology based on a novel resistance model. Background technique [0002] With the expansion of the application field of semiconductor devices, semiconductors are required to be strong in high temperature, strong radiation and high power environments in special occasions, so silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO), diamond , aluminum nitride (AlN) as the representative of the third generation of semiconductor materials on the stage of history. [0003] Compared with the first and second generation semiconductor materials, the third-generation semiconductor materials represented by GaN materials have the following advantages: [0004] 1. The band gap of GaN material is very large (3.39eV), which makes it have good heat resistance and can work above 500 °C; [0005] 2. The GaN material has a high breakdown...
