Abstract
A wireless wake-up receiver includes multiple signal chains each signal chain being coupled to continuously receive a signal from a respective antenna and to provide a respective detected pattern at a signal chain output. Each signal chain includes a first path having a mixer-first architecture and operates in a bandpass-mode using differential signals. The wireless wake-up receiver also includes a digital correlator operable to receive the respective detected patterns and to determine whether one of the respective detected patterns is equal to a desired pattern.
