A headwear device is provided for the comfortable and secure positioning of a hat on the head of an animal such as a dog. The device features a body having an interior adapted to engage the head of the animal with side portions having openings therein adapted for encircling the ears of the animal during wearing of the headwear. A position-adjustable fastener adapted for locating under the chin of the animal, is slidably engageable with both of two straps connected to opposing sides of the hat body. A slide adjuster on both of the first and second straps may be employed to cinch both straps and tighten the engagement on the head of the animal.

Devices and methods of the invention use a plurality of Fin structures and or combine a planar portion with Fin structures to compensate for the first derivative of transconductance, gm. In preferred methods and devices, Fins have a plurality of widths and are selected to lead to the separate turn-on voltage thresholds for the largest, intermediate and smallest widths of the MIS HEMT fins flatten the transconductance gm curve over an operational range of gate source voltage.
