Claim:
1. A switching device comprising: a first terminal and a second terminal; and a plurality of field-effect transistors connected in series between the first terminal and the second terminal, the field-effect transistors including a first end field-effect transistor connected to the first terminal and a second end field-effect transistor connected to the second terminal, each field-effect transistor including a gate having a plurality of fingers, a plurality of source fingers, and a plurality of drain fingers arranged such that gate fingers are interleaved between the source and gate fingers, the gate fingers of each field-effect transistor having a width such that the field-effect transistors have a distribution of gate width values where the first end field-effect transistor has a gate width value greater than the other field-effect transistors, and where the distribution of gate width values decreases from the first end field-effect transistor for at least half of the field-effect transistors to a minimum gate width value corresponding to a field-effect transistor between the first end field-effect transistor and the second end field-effect transistor, the minimum gate width value being less than a gate width value of the second end field-effect transistor.
