    摘要： A filter arrangement comprises a switching element coupled to a filter input, wherein the switching element is controllable by a reference clock signal. The filter arrangement further comprises an input storage element, an output storage element, and a first and a second auxiliary storage element. The first and the second auxiliary storage element can each be connected in parallel to the input storage element or to the output storage element depending on a switching signal. The output storage element is coupled to a filter output. The filter arrangement can be used as a loop filter in an analog-to-digital converter, wherein the output signal of the filter arrangement is quantized to provide an output word. Respective feedback signals can be generated from the output word and be provided to the storage elements.

    摘要翻译： 滤波器装置包括耦合到滤波器输入的开关元件，其中开关元件由参考时钟信号控制。 滤波器装置还包括输入存储元件，输出存储元件以及第一和第二辅助存储元件。 第一和第二辅助存储元件可以各自根据切换信号并联连接到输入存储元件或输出存储元件。 输出存储元件耦合到滤波器输出。 滤波器装置可以用作模数转换器中的环路滤波器，其中滤波器装置的输出信号被量化以提供输出字。 可以从输出字生成各个反馈信号，并将其提供给存储元件。
