Abstract: A photonic mixer device for multiplying an impinging optical signal with a reference electrical signal includes: a semiconductor substrate of a first conductivity type; two detector regions of a second conductivity type different from the first conductivity type; two biasing regions of the first conductivity type with a higher dopant concentration than the dopant concentration of the semiconductor substrate, each biasing region positioned near one of the respective detector regions, wherein an electrical field can be formed in the semiconductor substrate by applying a voltage bias between the biasing regions; two bias electrodes, which are isolated from the substrate and the biasing regions, wherein each bias electrode is only locally, partially or completely, covering an outer edge of one of the respective biasing regions.

Abstract: A depth mapping system includes a time of flight ranging system including structured and unstructured light sources, an optical sensor unit and a signal processing unit. The system time employs first and second time of flight ranging technique in respect of the optical sensor unit. The first and second time of flight techniques measure respective first and second distance ranges over a first and a second respective field of view. Measurement of the first and second distance ranges are respectively at a first angular resolution and a second angular resolution greater than the first angular resolution. The structured and unstructured light sources respectively operate in respect of the first and second time of flight techniques. First and second regions of the optical sensor unit respectively have the first and second fields of view associated therewith, and the structured source has a greater emission radiant intensity than the unstructured source.

Abstract: An apparatus (100) comprises a light source that emits light modulated selectively at first and second modulation frequencies. A photonic mixer cell (102) generates and stores a plurality of electrical output signals respectively corresponding to phase offset values applied in accordance with an indirect time of flight technique and in respect of the selected modulation frequency. A signal processing circuit processes a first number of the electrical output signals at the first modulation frequency to calculate a first measurement phase angle (φ1) from a calculated first measurement vector, and a second number of the electrical output signals at the second modulation frequency to calculate a second measurement phase angle (φ2) from a second calculated measurement vector. A phase angle difference (Δφ) between the first and second measurement phase angles (φ1, φ2) is then calculated and a correction value (φcorr) applied to the phase angle difference (Δφ) to yield an extended range phase angle (φext) for calculating a range.

Abstract: An edge crack monitoring system for an integrated circuit provided on a die, comprises a conductive trace comprising at least a first conductive path for allowing current in a first direction, and a second adjacent conductive path for allowing current in a second direction opposite to the first direction. Both adjacent conductive paths form at least one loop surrounding a semiconductor device on a die. The arrangement of the trace is adapted to provide compensation of EM interferences. The trace comprises two terminals being connectable to a detection circuit for detecting damages by generating a fault signal upon detection of disruption of the conductive trace due to a damage. The conductive trace comprises high resistance portions with a resistance of at least 1 kΩ, adapted for reducing self-resonance.
