Publication number: 20240184351Abstract: Described herein is a technology for a wakeup pattern—data stream correlation by a detector to provide a trigger condition for a microcontroller in a wakeup receiver (WuRX). For example, the detector includes a data packet layer with a plurality of index registers that are updated through sampling of data streams. A sample clock is coupled to each of the plurality of index registers to independently activate each of the plurality of index registers. A shared comparator will then compare the updated plurality of index registers to corresponding shift registers that are initialized with rotating wakeup pattern bits. Based upon a number of matching results, the detector generates a triggering signal that facilitates a low-power operating mode to a high-power operating mode change.Type: ApplicationFiled: February 9, 2024Publication date: June 6, 2024Inventors: Andreas Michael Schoch, Ernst Muellner
