Abstract:
A wakeup circuit includes an energy detection circuit and a wakeup signal generation circuit coupled to the energy detection circuit. The energy detection circuit is configured to, in response to receiving an input signal, generate a detect signal that is proportional to the input signal. The energy detection circuit is powered by the input signal. The wakeup signal generation circuit is configured to, in response to receiving the detect signal, generate a wakeup signal.
