摘要
An analytical model to calculate the small-signal parameters for GaAs/AlGaAs inverted high electron mobility transistors is presented. The model is based on a self-consistent solution of the Schrodinger and Poisson's equations and non-linear velocity-electric field (v(d) - E) characteristic to evaluate the small-signal parameters for this class of devices. These include transconductance g(m), drain resistance r(d), gate source capacitance C-gs and unity current gain cut-off frequency f(T). The analytical results are compared with the experimental data and show excellent agreement. (C) 2000 Elsevier Science Ltd. All rights reserved.
