Abstract: In one embodiment, an apparatus includes: a wake-up radio to issue a trigger signal in response to detection of a wake-up message in a radio frequency (RF) signal; and a second radio coupled to the wake-up radio, the second radio to wake up in response to receipt of the trigger signal. The wake-up radio may be coupled to the second radio without substantial loading, and may be configured with stacked circuits to reuse currents.
