Abstract: A low-dropout regulator for low voltage applications includes a buffer circuit being arranged between an output terminal of an error amplifier and a control node of a pass device. The buffer circuit includes a driver having a first transistor being embodied as an NMOS transistor. The output terminal of the error amplifier is coupled to the control node of the first transistor. The control node of the pass device is coupled to an internal node of a first current path including the first transistor. The low-dropout regulator has high load capability, even if an input supply voltage is very low.

Abstract: The peak comparator circuitry comprises a differential amplifier circuit having an output node to generate a differential amplifier output signal in response to an amplification of a difference of an input signal and a reference signal, and a comparator circuit having an output node to generate a comparator output signal. A feedback path of the peak comparator circuitry is arranged between the output node of the comparator circuit and the output node of the differential amplifier circuit. The proposed peak comparator circuitry allows for a low voltage supply, a low current consumption and a fast output validity.

Abstract: A lateral flow test device includes a test chamber having a detection aperture. The lateral flow test device also includes an optical detector configured to receive light from an assay test strip through the detection aperture when the assay test strip is provided in the test chamber. The test chamber is configured for manual feed of at least a portion of the assay test strip passed the detection aperture. The optical detector is configured to detect one or more tracking features associated with the assay test strip so as to determine when at least a test line on the assay test strip is detectable through the detection aperture.

Abstract: An optical absorbance spectrometer includes a sample housing, a light source and a spectral sensor. The sample housing comprises at least two sample cells configured to hold a sample, respectively, and includes an optical waveguide which is configured to guide light from an input side, through the sample cells, to an output side. The light source is operable to emit broadband light and is connected to the input side to couple emitted light into the optical waveguide. The spectral sensor is connected to the output side and operable to receive light from the optical waveguide and to detect the intensity of the received light at multiple wavelengths.

Abstract: A module assembly for the detection of X-ray radiation includes an X-ray sensor being configured to receive a photon of the X-ray radiation and to provide an electrical signal in response to the received photon. The module assembly further includes a system-in-package structure for processing the electrical signal, the system-in-package structure including an input/output terminal, a first interposer and a second interposer and an integrated circuit which are arranged in a stacked configuration in the system-in-package structure. The package structure can be assembled on all four lateral sides and is thus four-side buttable so that contiguous modules can be mounted on all four sides without a gap between pixels to read out data from large-pixelated detectors of the X-ray sensor.
