电荷域滤波装置
摘要：
提供一种电荷域滤波装置，该装置包括：多个跨导器，每个跨导器将输入电压转换成电流并输出该电流；以及滤波单元，其通过对多个充电器反复进行充电和放电来对所述多个跨导器的输出信号进行滤波，其中通过将与对所述充电器进行充电的充电时间长度相对应的第一脉冲和与所述多个跨导器中的每一个相对应的第二脉冲进行卷积来获得所述电荷域滤波装置的脉冲响应。
摘要（英）：

There is provided a charge domain filter device including a plurality of transconductors each of which converts an input voltage to a current and outputs the current and a filter unit that filters output signals from said plurality of transconductors by repeatedly charging and discharging a plurality of capacitors, wherein an impulse response of the charge domain filter device is obtained through convolution of a first impulse corresponding to a charge time length over which said capacitors are charged and a second impulse corresponding to each of said plurality of transconductors.
