Low Power Management Technology

Power Management, Power Gating and Low Power Design

Design for low power consumption and smart management of SOC devices to minimize current drain is one of the most complex and important elements in semiconductor design of today’s IC’s for use in mobile devices. Low power active and standby consumption is one of the most important performance and marketing criteria in design of any battery powered or ‘Eco-Friendly” device, ranging from mobile handsets, Bluetooth headsets, monitors, laptops to electric vehicles such as the Tesla or Nissan Leaf.

We’ve seen a variety of complex and innovative techniques in this area, ranging from transistor design at the submicron level to power gating techniques used in large SOC devices, from manufacturers such as Rohm, Qualcomm Snapdragon, Seiko Epson, Panasonic and Samsung Exynos products.
