Abstract

A novel IDDQ sensor circuit with high sensitivity thatoperates at a low supply voltage is proposed. The circuitdoes not need an I-V translator but is directly driven by anabnormal IDDQ. The circuit can operate at either 5-V VDDor 3.3-V VDD with the same design. Simulation results showthat it can detect a 16- mA abnormal IDDQ at 3.3-V VDDand can reduce the voltage drop and performance penalty ofthe circuit under test.
