Summary:
A DFT method of resistor string digital-to-analog converters (DACs) is proposed so as to be tested fully by supply current testing. Targeted defects are opens in the DACs. Testability of opens in testable designed DACs is examined experimentally. The results show that all of the opens in an N-bits testable designed DAC will be detected with test vectors of about 2(N-1) by supply current testing.
