Adaptive (Dynamic) Voltage (Frequency) Scaling – Motivation and Implementations
To optimize power-dissipation and reduce junction temperature while achieving processing performance
goals, various approaches are used to scale supply voltages to a systom on chip (SoC) that contains
This application report details the nomenclature, summarizes the parameters influencing powerdissipation,
and describes the implementation of one method known as adaptive voltage scaling (AVS).
This report also describes how an optimized a power-management integrated circuit (PMIC), such as the
TPS659038-Q1 device, can be used to implement this AVS method.
