    • In a slew rate limiter, a slew rate is limited so as not to pass a signal varying more abruptly than a wobble signal included in a difference signal generated by a differential amplifier, and this limited slew rate is used to process the difference signal to be outputted. That is, the slew rate limiter removes a signal varying more abruptly than a wobble signal included in a difference signal DIFO, and then outputs only the wobble signal. A DAC generates an offset voltage. An adder is used to add this offset voltage to the wobble signal from the slew rate limiter. The signal obtained by this addition as a slice level is compared by a comparator with the difference signal, thereby reproducing an LPP signal.
    • 在转换速率限幅器中,转换速率受到限制,以便不会比包含在由差分放大器产生的差分信号中的摆动信号更突然地变化的信号,并且该限制转换速率用于处理差分信号为 输出。 也就是说,转换速率限制器去除比包括在差分信号DIFO中的摆动信号更突然地变化的信号,然后仅输出摆动信号。 DAC产生偏移电压。 使用加法器将该偏移电压加到来自转换速率限制器的摆动信号。 通过该相加获得的信号作为限幅电平,通过比较器与差分信号进行比较,从而再现LPP信号。

    • A driving method for a solid state image pickup device, having four or more transfer stages as one transfer unit, includes reading signal charge from the charge accumulation regions to the vertical charge transfer channels. The reading step includes (b-1) applying the barrier forming voltage to a first transfer electrode to form a barrier of at least one stage per the transfer unit; (b-2) applying the read pulse to a second transfer electrode to read signal charge from a corresponding charge accumulation region to a corresponding vertical charge transfer channel; and (b-3) applying a cancellation pulse to a third transfer electrode spaced by at least one transfer stage from the first transfer electrode, the cancellation pulse cancelling out a potential change in the charge accumulation region to be caused by the read pulse.
