April 12, 2018, anysilicon

IDDQ is one of the methods for testing wafers or ASICs. IDDQ stands for the quiescent power supply current in CMOS circuits. When the circuit is not switching and the inputs are static.

An ASIC will draw less than 10uA in quiescent state. If the ASIC has a defect the IDDQ will be higher.
