Harmke De Groot, department director at imec, said: “The radio consumes the majority of the power of the total system and is one of the most critical components to enable these emerging applications. A low cost, area efficient radio design is an important catalyst for developing small sensor applications."
The radio achieves features a digital intensive RF architecture integrated with the digital baseband and an MCU. Several low voltage techniques are adopted to ensure sub 1V operation, as well as enabling a receive power consumption of 3.7mW and a transmit power consumption of 4.4mW.
Receiver sensitivity is said to be -93.5dBm, with a dynamic range from the sensitivity level up to -5dBm.
