摘要： A system of multiple concurrent receivers is described to process multiple narrow bandwidth wireless signals with arbitrary bandwidth and center frequency separation. These multiple receivers may provide a downconverted signal at the baseband frequency to process signal bandwidth using the lowest power consumption while using fully modular signal processing blocks operating at the low frequency. The concurrent receivers may operate from a single high frequency amplifier and may be derived from a low impedance point to reduce loading and improve scalability. The center frequency and bandwidth of each of the channels as well as phases of each of the channels may be independently reconfigured to achieve scalability, and on-chip test and calibration capability.

摘要： 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.
