摘要： Provided is a switched capacitor amplifier capable of outputting a stable output voltage. The switched capacitor amplifier is capable of operating so as to eliminate a charge/discharge time difference between an input capacitor (18) and an output capacitor (19). Accordingly, in a shift from a hold state to a sample state, for example, even if one terminal voltage (V2) of the output capacitor (19) abruptly increases to an output voltage (VOUT), another terminal voltage (Vs) of the output capacitor (19) does not increase abruptly. In other words, an input voltage to an internal amplifier (11) does not increase abruptly. Therefore, an output voltage of the internal amplifier (11) becomes stable and accordingly the output voltage (VOUT) becomes stable as well.

摘要： Provided is a photodetection device which is small in size and has excellent sensitivity. A photodetection device puts cathode terminals of photodiodes having different spectral characteristics into an open end state, and detects light intensity of a desired wavelength region according to a difference in electric charges that have been stored in those photodiodes in a given period of time. The photodiodes employ a system of storing electric charges, and hence even if a photocurrent is small, the photocurrent may be stored to obtain the electric charges required for detection, and the downsizing and high detection performance of a semiconductor device that forms the photodiodes may be achieved. Further, a wide dynamic range may be realized with an electric charge storage time being variable according to the light intensity, to intermittently drive an element required for difference detection at the time of difference detection so as to suppress electric power consumption, or to average the output so as to reduce flicker.

摘要： Provided is a comparator circuit that is capable of operating at high speed and canceling an offset voltage with high precision. The comparator circuit includes a second amplifier circuit for amplifying an output of an amplifier circuit and feeding back the amplified output to an input of the amplifier circuit. When the comparator circuit samples the input voltage, the second amplifier circuit conducts feedback and increases a gain to cancel the offset. Also, when the gain of the amplifier circuit is made lower than the gain of the second amplifier circuit, and the comparator circuit compares the input voltage, the comparing operation can be conducted at high speed by separating the amplifier circuit from the feedback of the second amplifier circuit.

摘要： A color-drift correcting method in an image forming apparatus includes a first and a second color-drift correcting. The first color-drift correcting includes correcting the color-drift amount in a sub scanning direction and a skew relative to the reference color image being based on each color-drift amount of at least three mark-patterns, each of which mark-pattern is formed each color image, so as to decide a corrected-image line as a virtual image line for each color, assumed when the color images are superposed onto a transfer media. A second color-drift correcting includes correcting the color-drift amount in the sub scanning direction so that the virtual image lines corresponding to each of the colors other than the reference color intersect with the virtual image line of the reference color at at least two points.

摘要： After detecting a speed fluctuation pattern per rotation of a photosensitive drum, a process that forms an image based on image data while causing the photosensitive drum to rotate at a nonstandard linear speed is executed as an image forming process by driving a process driving motor that drives the photosensitive drum to curb a speed fluctuation of the photosensitive drum by using a driving speed fine tuning pattern. Before executing the image forming process, a fine-tuning-pattern correcting process is executed for correcting the driving speed fine tuning pattern of the process driving motor, based on the nonstandard linear speed.
