Abstract:
While an IC chip is in idle mode with no power being supplied to the IC chip, the IC chip may be operable to detect a signal pulse received by the IC chip using energy associated with the signal pulse. The IC chip may be operable to control a control signal for a power switch using the energy associated with the signal pulse. The power switch may allow power to be provided to the IC chip based on the control signal. The IC chip may comprise a pulse detector, a latch circuit and an ON/OFF logic circuit within the IC chip. While the IC chip is fully powered and communication with a partner chip is finished, the IC chip may be operable to control the control signal to turn off the power switch for powering down the IC chip based on a turn-off signal.
