Abstract: In one example, a device to process analog sensor data is described. For example, a device may include at least one analog sensor to generate a first set of analog voltage signals and a crossbar array including a plurality of memristors. In one example, the crossbar array is to receive an input vector of the first set of analog voltage signals, generate an output vector comprising a second set of analog voltage signals that is based upon a dot product of the input vector and a matrix comprising resistance values of the plurality of memristors, detect a pattern of the output vector, and activate a processor upon a detection of the pattern.

Abstract: An apparatus includes an optical rib waveguide on a substrate, the optical rib waveguide further includes: a slab layer of silicon, a shallow rib of silicon in height that tapers laterally along a taper region, a deep rib of silicon that meets the shallow rib along the taper region of the shallow rib, and wherein the deep rib and the shallow rib have a same width, and wherein the shallow rib has a greater height than the deep rib, a core of silicon that tapers laterally in a range of 50-90% and extends on top of the deep rib and the shallow rib, and a cladding layer of silicon oxide that covers the slab, core, deep rib, and shallow rib.

Abstract: A circuit includes a startup circuit to provide a charging signal to initiate startup of a reference circuit. The startup circuit includes a detector circuit having a detector current path control, a level shifter having a level shifter current path control, and a charger circuit having a charger current path control. Each of the detector current path control, the level shifter current path control, and the charger circuit current path control enable current flow in the startup circuit when the charger turn-on signal is in the on-state and disable the current flow in the startup circuit when the charger turn-on signal is in the off state.

Abstract: In one example, a device includes a bus waveguide to carry a light of a carrier wavelength, a first ring waveguide with a first modulator, a first heater to adjust a resonance wavelength of the first ring waveguide, and a second ring waveguide with a second modulator. The first ring waveguide and the second ring waveguide are coupled to the bus waveguide and are to modulate the light of the carrier wavelength to impart one of at least four optical power levels to the light. In another example, a device includes, a bus waveguide, a first ring waveguide with a first modulator, and a second ring waveguide with a second modulator. The first ring waveguide and the second ring waveguide are coupled to the bus waveguide and are to modulate a light of a carrier wavelength to impart one of at least four optical power levels to the light.
