    摘要: A two-phase shift register comprises four serial registers each having an input section, a transfer section, and a lead-in section disposed between the input section and the transfer section. The input sections provide respective sequences of charge samples, the four sequences being offset in phase relative to each other by 90 o within the cycle of a clock signal. At least one of the serial registers comprises a first lead-in gate pair and a second lead-in gate pair over the lead-in section, the second lead-in gate pair being between the first lead-in gate pair and the transfer section. The first lead-in gate pair and the second lead-in gate pair are each driven at the frequency of the clock signal, the drive signal applied to the second lead-in gate pair being retarded in phase relative to that applied to the first lead-in gate pair by 90 o within the cycle of the clock signal.

    摘要: An output signal processing circuit for a CCD register, for example a horizontal output register of a CCD imager is provided. The CCD register includes an output precharge circuit with a capacitance, the voltage across the capacitance is supplied to an output terminal of the CCD register and has first, second and third durations repeatedly. The first duration is a precharge duration, the second duration is a reference duration and the third duraiton is a signal duration. The output signal processing circuit includes a clamp circuit(3) for clamping the output signal at the output terminal of the CCD in such a manner that the voltage of the reference duration becomes a stable clamp voltage, clip circuit (8) for clipping the output signal of the clamp circuit such that the voltage of the precharge duration is clipped to a clip level, and a low-pass filter (11)suppliedwith the output of the clip circuit(8) for generating the transferred signal.

    摘要: The sensor (FT) comprises a drive shift register (SR) which ensures that information is shifted in the sensor in accordance with the accordion principle. In the known shift register control performed by means of square-wave clock pulse signals (Q), it appears that horizontal stripes may occur in practice when the generated picture signal is displayed. According to the invention these stripes are eliminated by using a clock pulse with at least three levels, while the clock pulse signals may have a staircase or a sawtooth variation. This prevents faulty charge packet blending (t11p) caused by the square-wave clock pulses and results in an optimum charge transport (t11i).

    摘要: A sample-hold circuit comprises a large number of sample-hold elements (2Am, ..., 2Am+5), and a mult-­stage shift register (7A) for controlling sampling timings of the sample-hold elements, including a large number of stages corresponding to respective sample-hold elements, characterized in that each of stages (20, 20m, ..., 20m+5) of the multi-stage shift register includes an input gate (21, 21m, ..., 21m+5) for taking a signal shifted from the preceding stage thereinto, an output gate (22, 22m, ..., 22m+5) for shifting the signal taken in by the input gate to the succeeding stage, respective sampling timings of said sample-hold elements corresponding to respective stages being determined by signals taken in between the input and output gates through the input gates at the respective stages. Waveforms of output signals from respective stages for determining the sampling timing are not affected by interstage wiring capacity. Accordingly, where a multi-­stage shift register is made up as a folded array, unevenness occurs in the interstage wiring capacity, but such an unevenness has no bad influence on the sampling timing.

    摘要: L'invention concerne les dispositifs à transfert de charges. Elle s'applique spécialement mais non exclusi­vement aux dispositifs de lecture des charges engendrées dans des matrices photosensibles.
    On propose selon l'invention un duplicateur de charges capable d'engendrer avec un faible bruit une charge Qs* réplique d'une charge de référence Qs. La charge de référence est déversée par un injecteur (D1, AMP1, GP1, P1) sous une première grille de stockage (G1). La charge réplique est engendrée par un autre injecteur (D2, GP2, P2) sous une autre grille de stoc­kage (G2). Les grilles G1 et G2 sont reliées aux entrées d'un comparateur (AMP2); elles sont portées d'abord à un potentiel de référence haut Vref. Puis elles sont laissées flottantes et la charge Qs est déversée sous G1. Le comparateur bascule et autorise le deuxième injecteur à déverser des charges sous G2; le comparateur rebascule quand la quantité de charges sous G2 devient égale à celle sous G1.

    摘要: L'invention concerne les matrices photosensibles, et plus précisément le circuit de lecture connecté à chacune des colonnes de sortie de la matrice.
    Pour réduire le bruit de transfert de la colonne (Cj) vers un registre de sortie (RDS), on effectue N fois successivement un transfert de la charge Qs à lire de la colonne vers une zone de stockage intermédiaire, une duplication de cette charge et une sommation des charges dupliquées (Qs*), et une restitution de la charge Qs vers la colonne . Si les bruits de transfert sont décorrélés les uns des autres, le rapport si­gnal/bruit global est amélioré dans un rapport N 1/2 . Une fraction de la somme des charges répliques (par exemple la moyenne des N charges répliques) est transmise à la sortie et constitue le signal de sortie du circuit de lecture.

    摘要: This charge transfer device comprises transfer electrodes (700) and read electrodes (600). The read electrode operates in accordance with two modes. Where it operates based on the charge detection mode, a charge below the read electrode is read out in accordance with the floating gate system, so that a charge detection signal is produced. On the other hand, where it operates based on the charge transfer mode, the read electrode performs a function equivalent to the transfer electrode. This device further comprises selector means (400), thus permitting the read electrode to select either of two modes to operate in a selected mode. Since mode selection can be thus made according to need, crosstalk based on the charge detection signal can be suppressed.

    摘要: The invention relates to a charge-coupled device with an adjustable charge transport route comprising at least two ccd segments, which can be connected in series with each other by means of a switchable connection. This connection comprises an output diode for the first segment, an input diode for the second segment, and a switch, for example a MOS transistor, which is connected to the output diode and/or the input diode. The input diode and the output diode may be in the form of individual zones or in the form of a common zone. The invention, which offers the advantage that the transport time through the connection isindependent of the length of the form of the connection, can be used, for example, in programmable filters, (de)multiplexers, (de)scramblers etc.
