Controlled broadband load modules for generic noise injection at package and board level

Noise injection into power supply rails during chip validation can offer insight for effective power delivery design and to assist product certification. There are no available commercial solutions that offer broadband stimuli application for such aim. The paper suggests few implementations for such modules, emphasizing generic interfaces and the specific application pros and cons. Some prototyping attempts were made and both of their modeling and empirical results are included. The data indicate a strong contribution of the module interface parasitical properties to the resulting spectral range and distortion of the module loading stimuli versus the desired reference.
