It is designed to receive data modulated with on-off-keying in UMC 65nm CMOS technology and it employs uncertain-IF architecture to reduce the oscillator design constraints and to decrease power consumption. The wake-up radio consist of a single-ended active mixer, a five stage IF-amplifier and a differential envelope detector biased in weak inversion. The wake-up radio has been designed with to provide a trade-off between sensitivity and power consumption. The obtained sensitivity and power consumption is -78 dBm and 40.9 μW, respectively, with 1.2 V power supply.||URI:||http://hdl.handle.net/10553/55439||Source:||XXX Design of Circuits and Integrated Systems Conference (DCIS).
