A fast and sensitive built-in current sensor for IDDQ testing
Chih‐Wen Lu, Chung Len Lee, Jwu-E Chen · 2002
In this work, a fast and highly sensitive Built-in Current (BIC) sensor is proposed for testing static CMOS ICs. The sensor employs a current mirror and an I-V converter to achieve the high sensing speed and high resolution. The circuit is simple and occupies a small area, making it ideal to be integrated into the IC chip for the IDDQ application.
