    • A semiconductor integrated circuit device includes a pulse width expander circuit for expanding the pulse width of a pulse signal of the ECL (emitter coupled logic) level that has a very narrow pulse width, a level conversion circuit for converting the output signal of the ECL level of the pulse width expander circuit into a CMOS (complementary metal oxide semiconductor) level, and an internal circuit that is so connected as to receive the output signal of the level conversion circuit. In other words, the pulse signal having a narrow pulse width is expanded to have a pulse width which is sufficient for the level conversion circuit prior to performing the level conversion operation. Therefore, the level of the pulse signals having narrow pulse widths is stably converted.
    • 半导体集成电路器件包括用于扩展具有非常窄的脉冲宽度的ECL(发射极耦合逻辑)电平的脉冲信号的脉冲宽度的脉宽扩展器电路,用于转换ECL电平的输出信号的电平转换电路 的脉冲宽度扩展器电路转换成CMOS(互补金属氧化物半导体)电平,以及连接到接收电平转换电路的输出信号的内部电路。 换句话说,具有窄脉冲宽度的脉冲信号被扩展为在执行电平转换操作之前具有足够的电平转换电路的脉冲宽度。 因此,稳定地转换具有窄脉冲宽度的脉冲信号的电平。

    • A photodetector capable of improving dynamic range for input signals is provided. This photodetector includes a photoelectric converting portion, a charge separating portion, a charge accumulating portion, a barrier electrode formed the charge separating portion and the charge accumulating portion, and a barrier-height adjusting portion electrically connected to the barrier electrode. Undesired electric charges such as generated when environment light is incident on the photoelectric converting portion are removed by the charge separating portion. A potential barrier with an appropriate height is formed under the barrier electrode by applying a voltage to the barrier electrode according to an electric charge amount supplied from the charge separating portion to the barrier-height adjusting portion. Electric charges flowing from the charge separating portion into the charge accumulating portion over the potential barrier are provided as an output of the photodetector.
    • 提供能够改善输入信号的动态范围的光检测器。 该光检测器包括光电转换部分,电荷分离部分,电荷累积部分,形成电荷分离部分和电荷累积部分的势垒电极,以及与阻挡电极电连接的势垒高度调节部分。 当环境光入射到光电转换部分时产生的不期望的电荷被电荷分离部分除去。 通过根据从电荷分离部向阻挡高度调节部供给的电荷量向阻挡电极施加电压,在阻挡电极下形成具有适当高度的势垒。 作为光电检测器的输出,提供从电荷分离部分流过势垒上的电荷累积部分的电荷。
