METHODS AND APPARATUSES FOR ULTRA-LOW-POWER SYSTEM ON A CHIP (SoC) ACTIVITY WEARABLE DEVICES

摘要

An always-on chip incorporated inside an activity wearable device implemented as a System-On-a-Chip (SoC). The device includes a MCU and DSP and audio CODEC and a BLE circuit to detect user activation commands.;The user wakeup command is used to wake up the main application processor on the system.;Ultra low power consumption may be realized by implementing the CMOS die using sub-threshold technology and by using power and battery management algorithms based on the human activity detected by the integrated sensors.
