Abstract :
Further enhancements of a HEMT noise modeling procedure enables scaling of bias dependent noise models. This was experimentally verified through V-band using prematched structures utilizing the TRW 0.1 /spl mu/m gate length low noise process. With this procedure, it is now possible to scale device noise models obtained at microwave frequencies to millimeter wave frequencies with good correlation. The scaled models are further verified with Q- and V-band low noise amplifiers.
