Abstract

In this paper, we proposed OOK wake-up receiver (WuR) with the sampling technique. In this method, the power consumption of RF envelope detector, which is the most power hungry component in the receiver, is greatly reduced by the signal-level duty cycling (or sampling), and the original OOK modulated IF signal is recovered by a designed active IF bandpass filter, which consume only micro power. Using this novel method, a new wake-up receiver with the high sensitivity and the low power consumption is designed and implemented. According to our test, the lowest input RF power that the OOK modulated signal can be recovered is -70dBm, which is almost same as the sensitivity of envelope detector LT5538. Meanwhile, the power consumption of our WuR is about 310μW.
