Abstract

An ultra-low power wake-up receiver for wireless sensor network applications is presented. The 915MHz OOK receiver is based on the double-sampling RF power detector architecture. Together with an on-chip ADC, the receiver achieves -86dBm sensitivity at 10kbps, while consuming 123μW. Flexible sensitivity/data-rate/power consumption options are also possible. The receiver front-end is fabricated in a 90nm CMOS technology and wire-bonded in a QFN56 package.
