A hydrodynamic energy model is efficiently used for the simulation of a dual-gate lattice matched MODFET at room temperature. The results obtained give a good insight of the device physics and permit through the systematic use of the model to predict

The potential performance improvement achieved by reducing the gate length of GaAs MESFET's below 0.25 μm is investigated using a novel two-dimensional nonlocal numerical model. The charge, potential, and electron energy distributions in three devic

The surface potential effect in GaAs MESFETs causes a depleted zone to form not only between the source and gate, but also between the gate and drain. The consequences of this phenomenon on the device behavior, the DC and AC characteristics, and the

Starting from the "cascode" model of the dual gate microwave MESFET an analysis of its performance as a mixer is carried. In this approach, the modulation of the transconductance of the second FET as well as the "drain" resistance of the first FET by
