Imec and Holst Centre have developed a novel phase-tracking receiver bringing further power and cost reduction for the next generations of Bluetooth and IEEE802.15.4 radio chips.
The ultra-low power digital-style receiver is 3x smaller than the current state-of-the-art. It supports supply voltages as low as 0.85V and consumes less than 1.6mW peak. An innovative low power antenna impedance detection technique enhances radio performance, especially for wearables or implantable applications.
The ongoing evolution towards an intuitive IoT has created unprecedented opportunities in various application domains. However, the deployment of massive numbers of interconnected sensors requires ultra-low power solutions enabling multi-year battery life. To increase the autonomy of sensors, imec develops ultra-low power wireless technology for IoT applications, such as next-generation Bluetooth Low Energy and IEEE 802.15.4.
Especially in wearable or implantable devices, the antenna impedance can dynamically change due to variations in a device’s position or surroundings. This can deteriorate the radio’s performance and degrade battery lifetime. Imec demonstrated a fully integrated, sub-mW impedance detection technique for ultra-low power radios.
