The design has an <em>OIP3<\/em>\u00a0 linearity figure-of-merit that is 10-15 dBm above the baseline for a similar 1 mm width control device, and is achieved at a gate bias on the order of 100 mA\/mm or less, where the ratio of transconductance to the bias current gm1\/ID is particularly large (7 volt-<sup>1<\/sup>).<\/p>\n<p>However, this local maximum is very narrow with respect to barrier thickness and delta-doping. We find that parabolic grading of the channel composition increases the height and width of the peak, rendering the design stable to the presence of inevitable process variations.
