On the development of power supply voltage control testing technique for analogue circuits

This paper discusses a novel testing technique for analogue circuits. The theory behind its success in exposing defects normally unexposed by other testing techniques is presented. This is supported by simulation results and real IC tests. Due to its modest requirement to perform the test, this testing scheme is more attractive and beneficial. Methods of data analysis are also proposed to expose hard and soft defects. The advantages of the proposed testing scheme are fast to implement, uses simple test vector and does not require additional test circuitry on-chip
