CMOS 집적회로의 테스팅을 위한 새로운 내장형 전류감지 회로의 설계
Design of a Built-In Current Sensor for CMOS IC Testing
초록
This paper presents a Built-in Current Sensor that detect defects in CMOS integrated circuits using the current testing technique. This scheme employs a cross-coupled connected PMOS transistors, it is used as a current comparator. Our proposed scheme is a negligible impart on the performance of the circuit undo. test (CUT). In addition, in the normal mode of the CUT not dissipation extra power, high speed detection time and applicable deep submicron process. The validity and effectiveness are verified through the HSPICE simulation on circuits with defects. The entire area of the test chip is
