Summary: 
This paper presents a new built-in current sensor (BICS) that detects defects using the current testing technique in CMOS integrated circuits. The proposed circuit is a negligible impact on the performance of the circuit under test (CUT). In addition, no extra power dissipation and high-speed fault detection are achieved. It can be applicable in deep sub-micron process. The area overhead of the BICS versus the entire chip is about 9.2%. The chip was fabricated with Hynix 0.35 µm standard CMOS technology.
