Abstract
An electronic device may include a first transistor having a normally-on characteristic; a second transistor connected to the first transistor and having a normally-off characteristic; a constant voltage application unit configured to apply a constant voltage to a gate of the first transistor; and a switching unit configured to apply a switching signal to the second transistor. The first transistor may be a high electron mobility transistor (HEMT). The second transistor may be a field-effect transistor (FET). The constant voltage application unit may include a diode connected to the gate of the first transistor; and a constant current source connected to the diode.
