Abstract: The detection device comprises a photodetector configured to transform an electromagnetic signal into a representative electric signal. The detection device also comprises an amplifier having a first input terminal connected to a first terminal of the photodetector. An integration capacitor is connected to the output terminal of the amplifier and to the first input terminal of the amplifier. A first source of a reference voltage is connected to a second input terminal of the amplifier. A second source of a detector voltage is connected to a second input terminal of the photodetector. The first and second voltage sources are correlated so as to correlate the noise components.

Abstract: The detection circuit comprises a detector connected to an integration node. A bias circuit biases the detector between a first bias state and a second floating state. The potential of the integration node is at a target value when the bias circuit biases the detector to the first state and varies when the detector is in floating state. A measurement circuit without charge losses delivers a value representative of the potential present on the integration node N. A transfer circuit of the electric charges performs transfer of the electric charges from a stray capacitor of the photodiode to an integration capacitor. An output terminal delivers a voltage representative of the potential present on the second terminal of the first capacitor.

Abstract: The multispectral detection device comprises first and second photodetectors sensitive to two different wavelengths. The two photodetectors are connected to two integration capacitors of two different readout circuits. Two reset circuits are configured so as to initialise the two integration capacitors separately. A first synchronisation circuit is connected to the first readout circuit and to the synchronisation signal and clock signal generators. The first synchronisation circuit is configured in such a way as to define the frame by detection of a leading edge of the synchronisation signal, count the number of occurrences of a trailing edge of the clock signal, initiate or terminate a data acquisition phase when the number of occurrences of trailing edges is equal to a threshold value recorded in a register of the first synchronisation circuit.

Abstract: A method for producing the growth of a semiconductor material, in particular of type II-VI, uses a melt of the semiconductor placed in a sealed bulb under vacuum or under controlled atmosphere, the bulb being subjected to a sufficient temperature gradient for first maintaining the melt in the liquid state, then causing its progressive crystallization from the surface towards the bottom. The method further comprises an element capable of floating on the surface of the melt, and equipped with a substantially central bore, intended for receiving a seed crystal for permitting the nucleation leading to the preparation of a seed crystal, and also supporting the seed crystal above the melt while maintaining it in contact with the melt in order to permit the continued crystallization from the seed crystal by lowering the temperature gradient.
