In the next section, we present the IDDQ test technique that
serves to test analog ICs, and distinguish a fault-free from a
faulty circuit with respect to short (bridging) defects. This
technique is based on analysing the leakage current (IDDQ) of
the circuit under test using a Built-In Current Sensor. In our
investigation, we show that at the nanometer range (the 65 nm
node) IDDQ testing can be used to detect multiple bridging
defects which create a resistive path between VDD supply and
the ground.
