The radiation-sensitive device includes: a plurality of single photon avalanche diodes (SPADs), and processing circuitry configured to determine an intensity of incident radiation using at least one of the plurality SPADs. An amount of the SPADs used to determine the intensity of the incident radiation varies in relation to the intensity of the incident radiation. Also disclosed in an associated method of determining an intensity of radiation incident upon such a radiation-sensitive device, and uses of the radiation-sensitive device in an electronic-nose or point-of-care apparatus, or for ambient light sensing.

Abstract: A self-mixing interferometry sensor module includes at least two light emitters of the same type, a detector unit and an electronic processing unit. Each light emitter is operable to emit coherent electromagnetic radiation out of the sensor module and undergo self-mixing interference (SMI) caused by reflections of the emitted electromagnetic radiation from an external object outside the sensor module. The detector unit is operable to generate output signals indicative of the SMI of the light emitters, respectively. The electronic processing unit is operable to generate a difference signal from the output signals indicative of a movement of the external object.

Abstract: An optofluidic sensor operable to determine a concentration of a detergent component in a fluid includes a waveguide structure with an input optically coupled to a light source and a sensing region that is exposed to the fluid. A detection unit is optically coupled to an output of the waveguide structure and is configured to generate a detection signal based on an amount of light received from the output. A processing unit is configured to determine, from the detection signal received from the detection unit, the concentration of the detergent component in the fluid. The amount of light received from the output depends on a number of particles of the detergent component adsorbed on a surface of the waveguide structure within the sensing region.

Abstract: A high voltage driver circuit for devices such as non-volatile memories, in which a low voltage driver is combined in two different ways with a high voltage driver In one, input-independent embodiment, a low voltage driver (Q7, Q8) is connected directly in parallel with a high voltage driver, thereby providing a high voltage signal path for high voltage operations and a low voltage signal path for low voltage operations. In an alternative, partially input-dependent embodiment, a low voltage driver is connected to the output of a high voltage driver (Q9, Q10), which may comprise a partial level shifter (Q 1 B Q6).
