ABSTRACT:
A switching circuit includes at least two first semiconductor switches, each having a first input portion and a second input portion; range resistors that are provided between output portions of the first semiconductor switches and a device under test and that have different resistances from each other; a second semiconductor switch having an input portion connected to the output portions of the first semiconductor switches; and a differential amplifier having an input portion connected to the output portion of the second semiconductor switch and an input portion connected to ends of the range resistors, the ends being adjacent to the device under test. In accordance with a control signal, a desired one of the first semiconductor switches is connected to the first input portion and the second switch is connected to the output portion of the desired first semiconductor switch.
