    摘要: In a first period, a first and a second feedback capacitors each store an electric charge dependent on a voltage level of an input signal. In a second period, a first and a second output voltages are fed back respectively through the first and the second feedback capacitors respectively to a first and a second input terminals of a differential amplifier, and a first and a second sampling capacitors respectively store a positive charge dependent on a difference between the voltage level of the input signal and the first output voltage, and a negative charge dependent on a difference between the voltage level of the input signal and the second output voltage. In a third period, the positive and the negative charges respectively stored in the first and the second sampling capacitors are respectively transferred to the first and the second input terminals of the differential amplifier.

    摘要: A correlated double sampling circuit has a sampling capacitor equally divided into a plurality of portions. In the correlated double sampling circuit, an input signal is sampled at a plurality of sampling points and an averaging switch is closed to obtain an average value of a plurality of sampling values obtained by sampling. High frequency noise superimposed on the input signal is thus reduced and a difference between the average values of the plurality of sampling values obtained by sampling is output.

    摘要: A modified cross-section material having a thin part and a thick part in its widthwise direction is manufactured through a plurality of roll stages. Each rolling stage comprises of a set of a convex roll and a flat roll, wherein the convex roll has a convex part. The thin part is formed in accordance with the lengthwise expansion by the convex part of the convex roll, and the thick part is formed in accordance with the lengthwise expansion by a part other than the convex part of the convex roll.
