Abstract
A semiconductor device includes insulated and separated transistor elements successively connected to one another between ground potential and a predetermined potential. A transistor element at the GND potential side is a first stage and a transistor element at the predetermined potential side is an n-th stage. Resistance elements or capacitance elements are successively connected to one another in series between the GND potential and the predetermined potential. A resistance or capacitance element at the GND potential side is a first stage and a resistance or capacitance element at the predetermined potential side is an n-th stage. Gate terminals of the transistor elements at the respective stages excluding the transistor element at the first stage are successively connected to connection points. An output is taken from the terminal at the predetermined potential side of the transistor element of the n-th stage.
