Abstract:
A pin electronics, which inputs and outputs signal from and to an input/output pin of an electric part, provided in a testing apparatus that tests said electric part; comprising:a current source which outputs desired electric current; a first voltage generator which generates a desired voltage; and a diode bridge, which is connected to each of said current source, said first voltage generator, and said input/output pin of said electric part, that provides said desired electric current to said electric part and provides said desired voltage to said electric part; wherein: said first voltage generator has a current measuring unit that measures an electric current, which is input from said first voltage generator to said diode bridge; and said first voltage generator being connected to one terminal of said diode bridge that is different than a terminal to which said input/output pin of said electric part is connected.
