A versatile Control Network of power domains in a low power SoC
G. Reveret

With the development of more and more power-consuming mobile applications, the battery lifetime has become the biggest challenge of a low-power System-on-Chip (SoC). Success in designing a low-power SoC requires successive attention to five intertwined networks: the exchange network between functional blocks through data busses, the clock distribution network, possibly enabling clock gating and frequency …

A CMOS Duty-Cycled Coherent RF Front-End IC for IR-UWB Systems
2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)
L. Ouvry, G. Masson, F. Hameau, LETI CEA ; B. Gerbert Gaillard, Easii-IC ; B. Caillat, Dolphin Integration

Current consumption of an IR-UWB receiver is reduced thanks to duty-cycling techniques applied to the full analog chain, thus benefiting from the impulsive nature of the signal. The coherent architecture performs down conversion by mixing the incoming pulse with a locally generated 2.75ns pulse template and needs only a 1GHz frequency synthesis instead of a …

Active Texts: The Swiss Army Knife of the schematic editor SLED!

It is commonplace that suppliers of EDA simulators allow configuring the testbench from some schematic editor. Meanwhile, a gap in terms of functionalities remains between configuring the testbench from the schematic versus from the simulator control file. To fill this gap, and to avoid restraining simulator usage without losing the focus on the schematics, Dolphin …

Succeeding in Implementing a Low-Power SoC with Power Islands
SNUG 2015

With the growth of markets related to the Internet of Things, the requirements in terms of very low-power consumption for the connected “things” push SoC/ASIC designers and architects to hunt down mA, and even µA, from specification until first silicon prototype validation. The level of experience in low-power strategy definition and implementation is very different …
