Abstract

An electronic device includes a substrate, a first transistor and a second transistor. The first transistor is disposed on the substrate and has a first terminal electrically connected to a first voltage level, a second terminal and a control terminal. The second transistor is disposed on the substrate and has a first terminal electrically connected to the second terminal of the first transistor, a second terminal electrically connected to a second voltage level, and a control terminal electrically connected to the control terminal of the first transistor. Wherein a voltage value of the first voltage level is greater than a voltage value of the second voltage level.
