    Abstract: When a signal output by a solid-state image sensing device is clamped to a predetermined reference potential, a high voltage generated in a transfer suspension period after the clamping as generally supplied to an A/D converter is generated. A sample/hold output Va is clamped to a clamp level Vref over a period of time between a halfway point of time of a signal of a picture element preceding ahead by one line and the end of an inhibit period of transfer clocks of a signal output by an empty transmission unit via a first clamp pulse and a sample/hold output for the second picture element, or a subsequent one of an OPB unit is clamped to the clamp level via a second clamp pulse to prevent a signal output from exceeding a reference voltage from being supplied to an A/D converter at a later stage.

    Abstract: A switching circuit comprising a means for holding a signal or a DC component thereof, and a switching transistor for driving the holding means, wherein another means is included for shaping the trailing edge to be more obtuse in the fall of a driving pulse applied to a gate of the switching transistor. There is also disclosed a charge transfer device comprising a charge transferrer for transferring a signal charge, a charge-voltage converter for converting the transferred signal charge into a proportional voltage, and a driver for supplying a reset pulse to the charge-voltage converter so as to reset the capacitance thereof to a predetermined potential, wherein another a means is incorporated in the driver for shaping the trailing edge to be more obtuse in the fall of the reset pulse. Since the trailing edge of the reset pulse at the time of turning off the reset is rendered more obtuse, it becomes possible to reduce the coupling portion of the output waveform where the potential of a floating diffusion or a floating gate is varied by the capacitive coupling which is derived from the parasitic capacitance between a reset drain and a reset gate.

    Abstract: A CCD solid state imaging device has an overflow mechanism to discharge excess electric charges at the sensor section. An overflow level can be stabilized without adjustment. The CCD solid state imaging device includes an overflow barrier region for determining an amount of electric charges handled by a sensor section, and an overflow drain region for discharging excess electric charges at the sensor section adjacent to the sensor section. An intermediate region having the same potential as that of the sensor portion is provided between the overflow barrier region and the overflow drain region. Also, a CCD solid state imaging device includes linear sensors provided in a plurality of lines and vertical transfer registers provided at end of the linear sensors in the charge transfer direction of the horizontal transfer registers. When signal charges are overflowed in a part of the horizontal transfer register, signals of all pixels can be avoided from being destroyed. In a CCD solid state imaging device having linear sensors arranged in a plurality of lines, and vertical transfer registers provided at ends of the linear sensors in the charge transfer direction of the horizontal transfer registers, there is formed a limit region for limiting electric charges to a predetermined amount before electric charges are transferred from the horizontal transfer register to the vertical transfer register.
