Abstract

This paper analyzes the effect of variations in the parameters of an Integrated Voltage Regulator (IVR) and its impact on the power/performance of a system of IVR driven digital logic circuit. The coupled analysis of IVR and digital logic considering variations in the integrated passives, power train FETs and controller transistors shows, compared to an off-chip VR, variations in IVR induce much larger shifts in the operating frequency of the logic and total system power. Variations in the output filter passives cause most prominent variations in the system power and performance, particularly pronounced at low voltage operation of the core. We also show that the mean performance of the system can be traded-off to reduce the variability by modifying IVR parameters, such as controller zeroes or output capacitors.
