Abstract :
A large signal model is proposed for GaAs epitaxial layer resistor, which can be used in resistor design, characterization and circuit simulation. The resistor I-V behavior can be excellently fitted by a hyperbolic tangent expression with only two model parameters. By taking into account the nonlinearities, frequency dispersion, and parasitic effect, the proposed model accurately predicts DC, small signal S parameter, and power performances of resistors.
