Abstract :
A novel and more accurate approach to the measurement of mobility of GaAs HEMT devices is presented. The new approach employs high-order derivatives as a means of determining the parameters of the proposed new mobility equation. The results presented consider the behaviour of mobility in the linear and saturation bias regions.
