ABSTRACT:
The disclosure provides a circuit and method for activating an electronic device from a low power state. The activation circuit comprises: a first accelerometer located in the device to detect a movement of the device along a specific axis; a second accelerometer which is activated upon receiving a movement signal from the first accelerometer indicating a movement of the electronic device along the specific axis; an input device; and a monitoring circuit connected to the input device and an output of the second accelerometer, the monitoring circuit providing power to the input device when the second accelerometer indicates movement of the device that surpasses a threshold and then generating an activation signal to operate the electronic device in a higher power state utilizing a notable signal received from the input device.
