    摘要： A solid-state image pickup device of the charge-coupled type is improved in that the width W1 (as viewed in the charge transfer direction) of each of the transfer gate electrodes for generating transfer elements in the field shift mode, the width W2 (as viewed in the charge transfer direction) of each of the transfer gate electrode for generating potential barriers also in the field shift mode are selected so as to satisfy the following formula, and a buried channel junction depth X.sub.JBC of each of the vertical charge transfer paths are selected so as to satisfy W1>W2 and/or W2>2.multidot.X.sub.JBC. In the inventive image pickup device, the charge quantity transferred is increased without impairing the vertical resolution of the device.

    摘要： A solid-state CCD image pick-up device includes optoelectric transducing elements corresponding to pixels vertically and horizontally arrayed in a matrix forming column linear arrays defining a column direction and at least one vertical charge transfer path associated with a corresponding adjacent column linear array. Pixel signals are vertically transferred from the column linear arrays to the vertical charge transfer paths such that gate signals occurring at predetermined times are applied to gate electrodes of the vertical charge transfer paths to permit the pixel signals to be scan read by a horizontal charge transfer path. Switching elements are provided for transfer gate electrodes and a drive circuit sequentially generates drive signals for groups of gate electrodes during periods in which the switching elements are rendered conductive to allow a full frame scan read to be performed by supplying a predetermined number of timing signals to the gate electrodes. The pick-up device can be fabricated with high density integration and high pixel density and can be provided with an improved vertical overflow drain structure. The image pick-up device also provides an electronic shutter function having improved vertical resolution. A shift register for producing improved vertical resolution is also disclosed.

An integrator is provided at each of the input and output stages, and a third integrator is provided immediately preceding the output side integrator. In the case where two or more said polar networks are incorporated, an additional integrator is provided between the polar networks. The total number of all the circuits is selected to be even and equal to the order of the filter.

    摘要： In a switching circuit device using current mirror circuits, there are provided a first group of current mirror circuits wherein a plurality of signal currents supplied via input terminals are superimposed upon mirror currents and signal currents resulting from the superimposition are derived as new mirror currents; and a second group of current mirror circuits to which the new mirror currents are supplied. The output stages of the second group of current mirror circuits are connected to each other at a common point which in turn is tied to the output stage of a current mirror circuit for supplying a mirror current of a predetermined magnitude. An output terminal is led out of said common point. Bias voltage for said second group of current mirror circuits is controlled so that any desired signal current is selected from said plurality of signal currents.
