Radio frequency (RF) power conditioning for wake-up circuit

An electronic device, comprising:

• a first transceiver having a first antenna;
• a second transceiver having a second antenna, wherein at least one of the first and second antennae receives an electronic communication from a remote electronic device and in response at least one of the first and second transceivers generates a wake-up signal;
• a microcontroller configured to generate a power control signal indicating a receipt of power by the microcontroller by a power source;
• and
• a power conditioning circuit that processes the wake-up signal and the power control signal from the microcontroller and provides the power from the power source to the microcontroller, wherein the power conditioning circuit is configured to receive both the wake-up signal from the wake-up source and the power control signal from the microcontroller as separate input signals that are logically combined to control power delivery to the microcontroller.

A method for reducing an energy consumption of an electronic tag, the method comprising:

• receiving, by at least one transceiver of the electronic tag, an electronic communication;
• outputting, by the at least one transceiver, a first signal to a power conditioning circuit;
• and
• activating a microcontroller in response to a receipt by the power conditioning circuit of the first signal;
• wherein the power conditioning circuit is configured to receive the first signal including a wake-up signal from a wake-up source which is received from the microcontroller as an input signal separate from and combined with a second signal including a power control signal to control power delivery to the microcontroller.

An electronic device, comprising:

• a power source configured to provide power to the electronic device;
• at least one processor in a sleep mode wherein the at least one processor does not receive the power provided by the power source;
• a first circuit in communication with the at least one processor, the first circuit being configured to generate a wake-up signal;
• a second circuit in communication with the first circuit to receive the wake-up signal therefrom and in communication with the at least one processor, the second circuit being configured to enable power from the power source to pass to the at least one processor in response to receiving the wake-up signal from the first circuit,
• wherein, in response to receiving power from the power source, the at least one processor is configured to send a control signal to the second circuit that causes power to continue to pass to the at least one processor even if the first circuit ceases to generate the wake-up signal, the electronic device further comprising:
• a third circuit that is in communication with the first circuit to receive the wake-up signal therefrom and is in communication with the at least one processor to receive the control signal therefrom, the third circuit being configured to cause the second circuit to cause the power from the power source to pass to the at least one processor upon receiving either or both the wake-up signal and control signal.
