(a) Interior design circuit for modeling RTHEMT. The HEMT characteristics are: Level = 2, , , and . The RTD characteristics are: P/V ratio of at room temperature, the peak current density is and the area is 0.145  m2. (b) Solid line and dotted lines show a RTD and a FET I-V characteristic respectively. At certain the RTD curve intersects with the saturation FET curve in only one point (point A) which results in the flat current.
