    • There is provided a CML to CMOS converter comprising two current sources both connected between a first power supply, having a first potential, and a driving node, first and second push-pull drive stages each having a current path connected between a second power supply, having a second potential, and the driving node, and each having a control input for one half of a CML signal and an output node. Each of the two output nodes is connected to the control node of a respective one of the current sources, each current source being connected to decrease the current it supplies to the driving node if the potential of its respective output of the converter moves towards the potential of the first power supply.
    • 提供了一种CML到CMOS转换器,包括两个电流源,两个电流源都连接在具有第一电位的第一电源和驱动节点之间,第一和第二推挽驱动级各自具有连接在第二电源之间的电流路径, 具有第二电位和驱动节点,并且每个具有用于CML信号的一半和输出节点的控制输入。 两个输出节点中的每一个连接到相应一个电流源的控制节点,如果其转换器的相应输出的电位朝向电位移动,每个电流源被连接以减小其提供给驱动节点的电流 的第一个电源。

    • A method for ensuring path integrity in an optical switch is provided that essentially eliminates any occurrences of misconnected paths and enables new signal paths to be easily generated and existing paths to be switched. The method is suitable for use in optical switching devices that enable selective connection of optical signals received on a plurality of input fibers to respective output fibers, wherein the optical switching device includes a first array of mirrors disposed in a first mirror plane and a second array of mirrors disposed in a second mirror plane. In accordance with the method, all mirrors are maintained in signal paths so that undesired light is prevented from reaching any of the output fibers.
    • 提供了一种用于确保光开关中的路径完整性的方法,其基本上消除了错误连接路径的任何发生,并且使得能够容易地生成新的信号路径并且切换现有的路径。 该方法适用于能够将接收在多个输入光纤上的光信号选择性地连接到相应输出光纤的光开关器件,其中该光开关器件包括设置在第一镜面中的第一阵列的反射镜阵列和第二阵列 的反射镜设置在第二镜面中。 根据该方法,所有的反射镜都保持在信号路径中,从而防止不期望的光到达任何输出光纤。
