Performance Improvement By System Aware Substrate Noise Analysis For Mixed-signal IC

The market wants mixed ICs that are smaller and cheaper, and even provide advanced features. To satisfy this contradiction, many mixed ICs makers are reducing their bill of materials (BOM) cost by decreasing the amount of materials in the package or on a board. But these cost-effective methods can cause significant performance degradation with intensified coupling effects due to substrate noise... » read more

Power Integrity Optimization Cuts RF Substrate Noise

Our main focus is on dynamic voltage drop at 16-14-10nm and beyond, but the rise of the Internet of Things (IoT) prompted me to share some silicon measurement results that are relevant to the RF design community. Normally, power integrity (PI) is looked at in the time domain, but in this work we looked at it from a frequency spectrum perspective. Silicon measurements prove how shaping the dynam... » read more
