    摘要: The output terminal of a first voltage-current conversion circuit, which includes operational amplifiers and a resistor, is connected to the output terminal of a second voltage-current conversion circuit which includes operational amplifiers and a resistor, and also to the negative input terminal of the second voltage-current conversion circuit via a source follower as an impedance conversion circuit which is formed by an NMOS transistor and constant current source. Furthermore, the output terminal of the first voltage-current conversion circuit serves as the output terminal of a differential amplifier circuit. The positive-phase input terminal of the second voltage-current conversion circuit is connected to a reference voltage. Since the node of the current outputs of the first and second voltage-current conversion circuits has a high impedance, these circuits operate to equalize their output currents.

    摘要: A solid state image pickup device has a drive unit with an all pixel drive mode for reading all pixels in a horizontal direction and a pixel skip drive mode for reading pixels in the horizontal direction by skipping some pixels, and a plurality of read-out systems for reading pixels. In the all pixel drive mode, signals of pixels are divisionally read by the plurality of read-out systems, and in the pixel skip drive mode, signals of pixels are read by one of the plurality of read-out systems. In this manner, in the pixel skip drive mode, the power consumption can be reduced and a difference between output signal levels to be caused by a variation in characteristics of elements of the read-out system can be suppressed.
