Improved Efficiency

By Bhanu Kapoor We constantly hear about process technology advances and their impact on power consumption of ICs, but the power management techniques have remained the same over last few process technology generations. Power gating, dynamic voltage and frequency scaling, and threshold voltage scaling have been the key power management techniques since the 90nm process technology. Clock gating... » read more

Choosing A Power Delivery Network For SoCs

By Bhanu Kapoor The design and selection of an SoC power delivery network (PDN) presents unique challenges, and its design is critical to achieving power consumption goals of the design. This is true when your PDN is external and based on off-the-shelf components as well as when it is being designed on-chip as part of the SoC. This article explores the external situation. Power archit... » read more
