PURPOSE:To isolate an input and output by connecting a 2nd super lattice diode to a resistor connected across a 1st super lattice diode to form a loop, connecting an input line, a bias line and an output line to the 1st super lattice diode, thereby fixing the other end of the resistor connecting to the input line to a prescribed potential. CONSTITUTION:The super lattice diodes 2, 1 of a structure where two kinds of semiconductors different in electronic affinity are used as 2-terminal elements, each one terminal of the two resistors 3, 4 is connected across the 1st super lattice diode 2, and the 2nd super lattice diode 1 is connected to each other terminal of the two resistors 3, 4 to form a loop. Then the input line 5 is con nected to one terminal of the 1st super lattice diode 2, the bias line 7 and the output line 6 are connected to the other terminal, and the other terminal of the resistor 4 connected to the input line 5 is fixed to a prescribed potential. Thus, the input section and the output section are isolated to isolate the input current and the output current.
