Abstract: Isolators having a back-to-back configuration for providing electrical isolation between two circuits are described, in which multiple isolators formed on a single, monolithic substrate are connected in series to achieve a higher amount of electrical isolation for a single substrate than for isolators formed on separate substrates connected in series. Discrete dielectric regions positioned between isolator components forming an isolator provide electrical isolation between the isolator components as well as between the isolators formed on the substrate. The back-to-back isolator may provide one or more communication channels for transfer of information and/or power between different circuits.

Abstract: A wireless sensor node is described. The wireless sensor node may include a wake-up circuitry configured to awaken the sensor when a request is received. The sensor may be placed in a sleep mode, thus saving battery usage until a wake-up signal requesting use of the sensor is received. Powering of the wake-up circuitry may be supplied through energy captured using an energy harvester. In one example, the energy for powering the wake-up circuitry is extracted from the same signal used for awakening the sensor. The wireless sensor mode may operate in a passive mode, in which the energy for powering the wake-up circuitry is harvested, or in a power supply-assisted mode, in which some of the power is provided by a power supply. High quality factors filters may be used to increase the signal-to-noise ratio of the wake-up signals, thus improving the node's ability to recognize activation requests.
