摘要： A signal voltage dividing circuit in which two switched capacitors each including an input terminal, an output terminal and a capacitor connected selectively to the input terminal or the output terminal are connected in series and driven in opposite phase with each other. A holding capacitor is connected between the junction of the two switched capacitors and a reference potential. An input signal is supplied across the two switched capacitors to produce a divided output signal from the junction of the two switched capacitors.

摘要： A liquid crystal drive controller comprises first lines drawn from the input terminals of a strobing comparator, first external terminals capable of connecting the first lines to strobing transmission lines, second lines drawn from a strobing offset current source, and second external terminals capable of connecting the second lines to the strobing transmission lines. The first lines and the first external terminals, and the second lines and the second external terminals are electrically insulated from each other on the liquid crystal drive controller. First wires and second wires are connected to strobing terminals so that the first wires are not included in the strobing offset current path, thereby eliminating a shortage of margin.
摘要翻译：液晶驱动控制器包括从选通比较器的输入端引出的第一线，能够将第一线连接到选通传输线的第一外部端子，从选通偏移电流源引出的第二线，以及能够连接第二条线到选通传输线。第一线路和第一外部端子以及第二线路和第二外部端子在液晶驱动控制器上彼此电绝缘。第一导线和第二导线连接到选通端子，使得第一导线不包括在选通偏移电流路径中，从而消除边缘的不足。

摘要： A time constant circuit capable of switching the characteristic, which is realized by a combination of an equivalent resistor made up of a switched capacitor and an ordinary capacitor, comprises a capacitor of the switched capacitor or the time constant circuit connected in parallel to a series circuit including a switching device and an additional capacitor. The characteristic is switched by turning on and off the additional capacitor by the switching device. The direct connection of a plurality of equivalent resistors with a plurality of switched capacitors and ordinary capacitors makes up an equalizer. The capacitor making up a switched capacitor is connected with a switching device and an additional capacitor so that the frequency characteristic of the equalizer is switchable by turning on and off the switching device. Each of the capacitors making up the switched capacitors, the capacitors making up the time constant circuits and the additional capacitors has an end thereof grounded. All the elements are thus capable of being formed in the same integrated circuits.
