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