Abstract:
A method of operating a semiconductor component having at least one field effect transistor, the method comprising:turning on the field effect transistor; and operating the field effect transistor in an on-state to produce a drain-to-source current comprising: at least first and second portions of the drain-to-source current, the first portion of the drain-to-source current produced by a first region of the field effect transistor, and the second portion of the drain-to-source current produced by a second region of the field effect transistor, wherein: the field effect transistor has a center closer to the first region than to the second region; the first portion of the drain-to-source current divided by an area of the first region is less than the second portion of the drain-to-source current divided by an area of the second region; the first region has a first value of a characteristic selected from the group consisting of gate-to-source voltage, channel length, channel width, gate oxide thickness, and channel mobility; the second region has a second value of the characteristic different from the first value of the characteristic; and the first value produces the first portion of the drain-to-source current and the second value produces the second portion of the drain-to-source current.
