GaAs Resistor Model Predicting Harmonic, Transient and Breakdown
A comprehensive nonlinear model of GaAs resistor is. developed based on DC, pulse and power measurements. The. model accounts for electrical and thermal feathers such as. velocity saturation, self-heating and breakdown effects. The. resistor nonlinearity is mainly due to the velocity saturation
