Power-Delivery Network Challenges Grow


By Ann Steffora Mutschler Physics is forcing convergence in the SoC power delivery network, whose job is to ensure that every device on a chip has a robust and stable voltage so it can meet its expected functionality and timing. In the past, chip design, package design and board design were separate disciplines, guard-banded to ensure that all the parts worked well together. Today, given t... » read more

Making Power Delivery Networks Better


Careful design of power delivery networks can make the difference in whether a chip manages power effectively or fails completely. This impact of cost and other factors in the design process has not gone unnoticed. Aveek Sarkar, vice president of customer support and product engineering at Apache Design Solutions, pointed to the iPhone as an example, where 50% or more of the bill of material... » 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
