Japan-based Renesas Electronics is the newest member of Imec's ultra-low power (ULP) wireless systems programme having entered a joint research project at Holst Centre, aimed at improving ULP wireless technologies for short-range communication such as automotive and industrial sensor networks.

Renesas will work closely with the Holst Centre to develop multi-standard radio solutions for small battery-operated or harvested wireless handheld devices. Researchers from Renesas will reside at Holst Centre in Eindhoven, Netherlands, to closely collaborate with Imec's research team.

By combining advanced ULP design IP and efficient low power circuits, ULP radios achieve high quality performance and reduce power consumption by a factor of three to ten lower than today's radios. The radios are also compliant with several wireless standards, such as Bluetooth Low Energy (2.4GHz band) and ZigBee (2.4GHz band).

"Various applications of sensor networks for a smart society need ultra-low power wireless communication technologies. So we develop innovative RF architectures and circuit technologies for them," said Renesas Senior Manager Koichi Yahagi.

"After five years of successful collaboration in our Green Radio programme, we are pleased that a prominent semiconductor company as Renesas now joins our ULP wireless systems R&D. We look forward to developing enhanced ULP solutions contributing to the realisation of the internet of things in mass market applications," said Holst Programme Director Harmke de Groot. During last year's International Solid-State Circuit Conference, Imec and Renesas presented a SAR ADC architecture, which they claim addresses the need for much faster low-power ADCs with small form factor (see Imec, Renesas roll 250 MSPS ADC for Wi-Fi, LTE-A).
