Abstract :
In this paper, we present an ultra low-power Wake-up Receiver front-end operating in the 868/915 MHz ISM band. It targets short distance body area networks. Its power consumption is only 126 uW, including a low-power on-chip ring oscillator. Since the receiver targets small transmission distances, up to 10 m, sensitivity is traded against power consumption. This is achieved by removing the LNA and making all the gain at the low IF frequencies. The receiver sensitivity is -65 dBm at a BER of 0.1%.
