A dual gate cascade amplifier includes a first transistor and a second transistor electrically connected in series, the second transistor including a first parallel transistor and a second parallel transistor, the first parallel transistor and the second parallel transistor being electrically connected in parallel, a first channel electrically connecting a first end channel region of the first transistor and a second end channel region, wherein one of the first or second end channel regions is a source and the other of the first or second end channel regions is a drain, the second end channel region being a common end channel region shared by the first and second parallel transistors, and a second channel electrically connected to the second end channel region and extending away from the first transistor.
