    摘要: An image sensor of the present invention prevents the phenomenon that surrounding background of a bright object reflecting or emitting strong light like the sun is presented at dark and improves image quality of the image sensor by controlling the brightness of the bright object. The image sensor using correlated double sampling technology which outputs data of an object by using difference between a reset voltage signal and a data voltage signal of a unit pixel includes a plurality of unit pixels arranged in a matrix, each outputting the reset voltage signal and the data voltage signal; a plurality of clamping means, each coupled to each unit pixels for clamping up the reset signal to a predetermined voltage level; and a voltage controlling block for adjusting voltage level supplied to a gate of each of clamping means.

    摘要: A hybrid-level charge recycling method for use in implementing low power LCD column drivers. By having external capacitors of the column driver drive the same column lines of the LCD, the need for a polarity reversing circuit is eliminated, and the time necessary for charge recycling, as well as the amount of power consumed, is reduced. As a result, the multi-level recycling operation in column driving IC is made more practical.

    摘要: Disclosed is a design method for plating of a printed circuit board (PCB) strip, in which a main plating line is optionally formed on a component side, a solder side, or an inner layer of the PCB strip by modifying a sub-plating line of the PCB strip used to manufacture a semiconductor chip package, and a method of manufacturing the semiconductor chip package using the same. Therefore, an excellent semiconductor chip package is manufactured without a short when the PCB strip is cut using a sawing machine because misalignment of main plating lines of the solder side and the component side of the PCB strip is avoided, and an interval between PCB units is reduced to desirably increase the number of PCB units in the PCB strip without the short when the PCB strip is cut.
