Abstract
In this paper, we present a portable SOS device with wireless communication. This device is based on all-digital-phase-locked-loop (ADPLL). A wake-up mode is implemented for low power consumption. With extra biological sensors attached to the users, the device is awakened by abnormal signals and actively sends a SOS signal for help. Moreover, it can use those sensors to collect information from users. This information can be modulated to RF frequency and sent out along with the SOS signal. The SOS device also can be used in passive mode with a SOS button in some emergency situations.
