Abstract :
This paper presents an 868 MHz wake-up radio using uncertain-IF architecture for wireless sensor network. 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.
