Abstract :
In this paper the harmonic balance is used to simulate the large signal I-V spectra of the intrinsic simulation model that are further used to fit a 3-dimensional electro-thermal polynomial model of the IDS - VDS - VGS nonlinearity. The fitted model is used to analyse the amount of self-heating distortion. To get reliable results a correct model for the thermal circuit of the simulation model is required. Also. strongly correlating control signals cause the system to be difficult to solve. To reliably the IDS different test setups need to be considered.
