摘要： A circuit is designed with a first lower conductor (500) having two ends. One end of the first lower conductor is coupled to a first signal source (386). A first upper conductor (544) has two ends and is spaced apart from the first lower conductor by a distance less than an allowable spacing between adjacent lower conductors. One end of the first upper conductor is coupled to a second signal source (384). A second upper conductor (508) has two ends. One end of the second upper conductor is coupled to another end of the first lower conductor for receiving a signal from the first signal source. A second lower conductor (552) has two ends and is spaced apart from the second upper conductor by a distance less than the allowable spacing between adjacent lower conductors. One end of the second lower conductor is coupled to another end of the first upper conductor for receiving a signal from the second signal source. Since the upper and lower conductors are spaced apart by a distance less than an allowable spacing between adjacent lower conductors, layout area is conserved. Total resistance of conductors connected to each signal source is the same, so signal delay is the same.
摘要翻译：电路设计有具有两端的第一下导体（500）。第一下导体的一端耦合到第一信号源（386）。第一上导体（544）具有两个端部，并且与第一下导体间隔一个小于相邻下导体之间允许间隔的距离。第一上导体的一端耦合到第二信号源（384）。第二上导体（508）具有两端。第二上导体的一端耦合到第一下导体的另一端，用于接收来自第一信号源的信号。第二下导体（552）具有两个端部，并且与第二上导体间隔一个小于相邻下导体之间允许间隔的距离。第二下导体的一端耦合到第一上导体的另一端，用于从第二信号源接收信号。由于上导体和下导体间隔距离小于相邻下导体之间的允许间距，所以布局面积是保守的。连接到每个信号源的导体的总电阻是相同的，因此信号延迟是相同的。

摘要： A densely integrated pixel, fabricated by CMOS technology, comprises a photodiode formed by a n-well, with cathode, surrounded by a p-well; a reset MOS transistor formed such that its polysilicon gate is positioned, for diode control, across the junction formed by p-well and n-well regions, and its source is merged with the photodiode cathode; and a sensing MOS transistor formed such that its source is combined with the drain of the reset transistor and its gate is electrically connected to the source of the reset transistor. In the pixel of the invention, the photodiode leakage current is greatly reduced, because no n+/p-well junction is connected to the photodiode, and the fill factor is improved, because the pixel size is much reduced.
