ULTRA-LOW-POWER RADIO FOR SHORT-RANGE COMMUNICATION |
摘要 |
A wake-up function is provided for a low power radio. The radio includes: an antenna, a rectifier, and a comparator. The rectifier is configured to receive an RF signal from the antenna and generates an output having a magnitude that decreases in the presence of the RF signal. The comparator compares the output from the rectifier to a reference signal and outputs an activation signal for another radio component. In response the activation signal, the radio component will transition from a low power consumption mode to a higher power consumption mode. In this way, the rectifier and comparator cooperatively operate to perform a wake-up function in the presence of an RF signal. |
