Abstract:
This paper proposes a bias-dependent description of the HEMT noise sources that is optimized with respect to implementation in large-signal compact models. The noise is described as a function of drain current instead of smallsignal parameters like the transconductance in order to maintain consistency between the small-signal and large-signal world.
