摘要: IDDQ testing has become a powerful tool for improving the quality of CMOS integrated circuits. One drawback this is its speed--often compromising speed accuracy, or vice versa. Given that well-designed part will have very low quiescent current, accuracy cannot be sacrificed; given test time perhaps most expensive an IC's final cost, sacrificed. This article describes QuiC-Mon, loadboard mounted circuit which capable offering both and accuracy--over 1-MHz measurement rates at sub-mA accuracy.
