Abstract: This specification discloses methods and devices to enable high resolution configuration of a low-power wake-up detector (LP Detector), which in turn is implemented allowing for very coarse threshold detection (i.e., the detectable threshold levels are widely spaced apart from each other) due to power consumption and design reasons. Based on this invention, the detection resolution can be enhanced from 10 mV steps to <1 mV steps. This makes the detection configuration more accurate, which allows for improved calibration, and reduces false wake-ups by smartly controlling hardware at no additional cost in power consumption. In some embodiments, the invention to enable high resolution configuration of a low-power wake-up detector (LP Detector) can be implemented by using a wake-up threshold control to control both a low-power wake-up detector (LP Detector) and an attenuator belonging to a receiver.
