  • Patent number: 5606367
    Abstract: A solid state imaging device includes a plurality of picture photosensitive pixels (pixel trains P.sub.1 -P.sub.n) for generating signal charges corresponding to an incident light amount, a shift gate (12) and a charge coupled device (CCD) register. (13) for sequentially transferring the signal charges outputted from the picture photosensitive pixels, and a monitor photosensitive pixel for generating signal charges in proportion to a mean value of the incident light amount of a predetermined number of the picture photosensitive pixels. The device further includes a single output circuit for converting both signal charges, one of which are generated in the picture photosensitive pixels and transferred through the shift, gate and CCD register, and the other of which are generated in the monitor photosensitive pixels, into an output signal, thereby providing the solid state imaging device capable of accurately measuring a mean value of the signal charges of the picture photosensitive pixels.

  • Patent number: 5591996
    Abstract: A device for producing an output voltage which is proportional to an applied magnetic field. The device includes a plurality charge injection regions, a corresponding plurality of charge exit regions, and a charge transfer region. The charge transfer region includes gate electrodes which serve to propagate at least one isolated charge packet across the charge transfer region in a predetermined direction from the charge input region to the charge output region. The charge packet is subject to the applied magnetic field which is perpendicular to the charge transfer region so as to induce a resultant potential that is orthogonal to both the applied magnetic field and the predetermined direction. Furthermore, the resultant potential effects a lateral redistribution of charge carriers in the packet. A recirculation configuration allows for a recycling of the packet from the output region back to the input region in order to accommodate a continuation of the redistribution of charge carriers.

  • Patent number: 5530275
    Abstract: The invention relates to a semiconductor device with which input signals can be weighted and the weighted input signals can be summed, and which in conjunction with a neuron can be used, for example, as a synapse in a neural network. The device comprises a number of switched capacitances with a common capacitor plate formed by a surface region 3 in a p-type substrate 1. The region 3 is connected to the inverting input of an amplifier 11 whose +input is connected to a reference voltage and whose output 12 supplies the summed output signal. The output 12 can be fed back to the input 3 via switch S. The other plate of the capacitances is formed by an electrode 6a, 6b, 6c, which can be switched between a reference voltage and an input source. The weight factors are stored in the form of electric charges on a floating gate 5a, 5b, 5c, which is provided between each input electrode 6 and the surface region 3.

  • Patent number: 5381177
    Abstract: A CCD delay line comprises of first, second and third transfer regions which are formed in a semiconductor substrate. Output portions of the second and third transfer regions are connected to a differential amplifier. The output terminal of the differential amplifier is connected to input sources of the first and second transfer regions. The third transfer region is able to carry at most 30% of maximum amount of charge which the first and second transfer regions can carry. A signal is supplied from a signal source through a clamp circuit to an input gate electrode of the first transfer region. Bias changing means independently change one of an input bias voltage supplied to the input gate electrode of the first transfer region and a reference bias voltage supplied to an input gate electrode of the second transfer region.
