Abstract: 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.

Abstract: In some examples, an integrated circuit comprises: a semiconductor die including a semiconductor substrate, a dielectric layer on the semiconductor substrate, and a metallization structure encapsulated in the dielectric layer, in which the semiconductor substrate includes a transistor having a first current terminal, a second current terminal, and a channel region between the first and second current terminals, and the dielectric layer has a sensing side facing away from the semiconductor substrate; an insulation layer on the sensing side; a sensor terminal on the sensing side and over the channel region; and a restriction structure including an opening and a rigid silicon-based fluidic structure, in which the silicon-based fluidic structure is on the sensing side and encapsulates a fluid cavity on the sensing side, the sensor terminal is in the fluid cavity, and the restriction structure is configured to transport a fluid by microfluidic diffusion.
