Abstract:
A semiconductor device includes a plurality of unit cell transistors on a common semiconductor structure, the unit cell transistors electrically connected in parallel, and each unit cell transistor including a respective gate finger. Respective threshold voltages of first and second of the unit cell transistors differ by at least 0.1 volts and/or threshold voltages of first and second segments of a third of the unit cell transistors differ by at least 0.1 volts.
