ABSTRACT:
A system for providing a reference voltage includes a tester adapted to provide a predetermined current, a first ground pad connected to a ground voltage of the tester, a second ground pad connected between the tester and the first ground pad, the second ground pad being connected to the tester through first and second resistors, a reference voltage pad connected to a node between the first and second resistors, the reference voltage pad adapted to provide a test reference voltage, and a multiplexer connected to the reference voltage pad, the multiplexer configured to output the test reference voltage as a reference voltage during substantial voltage variation.
