Improving battery-powered device operation time thanks to power efficient sleep mode
S. Genevey, C. Dominguez

Allowing battery-powered devices to run, without battery recharge, for years rather than months, partakes in enhancing significantly end-user satisfaction and is a key point to enabling the emergence of IoT applications. Numerous applications, such as M2M, BLE, Zigbee…, have an activity rate (duty cycle) such that the power consumption in sleep mode dominates the overall …

Standard cell libraries for Always-On Domain
D. Maurer

Standard-cell library offering is usually divided in three categories: 6/7-track library for cost driven requirements, 8/9-track library for mainstream requirements and 10/12-track library for high-speed requirements. Standard cell Libraries often includes Multi Vt / Multi-channel-length cells to provide further flexibility to achieve the best PPA trade-offs. However, the advent of battery-operated devices, which spend most …

How to succeed a true low-power Always-On Domain?
FLIPPERS: News on standards for Systems-on-Chip

optimize your AoN domain to reach low-power The specificity of numerous battery-powered applications (such as Wearables, IoT, Wireless communication…) is to spend most of their time in a sleep mode (> 99%). In many cases, the analysis of the energy consumed at the battery level in each power mode shows that the power consumption in …
