PowerSmart® - Low-Power Design Methodology
Power considerations have become a dominant factor in system design, especially in portable, battery-powered systems. Currently, system designers must work closely with both circuit and foundry engineers to manage power, requiring cross-functional expertise and straining resources for the integrated approach. At Faraday, we recognize the difficulties of system design and have developed the PowerSmart® design service to help our customers expedite their ideas into silicon
