    • A first type of merged power MESFET device includes two monolithically integrated MESFETS. The MESFETS share common sources and gates, and are sized so that one MESFET may be used as a power device while the other is used as a current-sense device. A second type of merged power MESFET device includes two monolithically integrated MESFETS. The MESFETS share a common region which serves as the source for one MESFET and the drain for the second MESFET. This allows the two MESFETS to function as the high and low-side switches for a buck or boost regulator. A third type of merged power MESFET device combines the high and low-side switches with a current-sensing device.
    • 第一种合并功率MESFET器件包括两个单片集成的MESFETS。 MESFETS共享共同的源极和栅极,其尺寸使得一个MESFET可以用作功率器件,而另一个用作电流检测器件。 第二种合并功率MESFET器件包括两个单片集成的MESFETS。 MESFETS共享一个公共区域,其作为一个MESFET的源极和第二个MESFET的漏极。 这允许两个MESFETS用作降压或升压稳压器的高侧和低侧开关。 第三种合并功率MESFET器件将高端和低端开关与电流检测器件相结合。
