摘要
提出用运算跨导放大器和电容（简写ＯＴＡ－Ｃ）实现的ＰＲＢ型带通滤波器。它可以方便地改变中心频率的带宽。对这种滤波器可能的输入电压最大值，以及一些非理想因素的影响进行了初步的讨论。通过计算机辅助分析（简写ＣＡＡ）和分立组件电路的实验，验证了此设计方法的可行性以及建立这种滤波器设计专家系统的可能性。
A new bandfilter is provided by applying the OTA-C technology. The PRB bandfilter makes it possible to realize the variation of central frequency and bandwidth. This artitcle also gives fundamental discussion in its possible maximal input-voltage,and the influence of some non-ideal elements. The article proves the possibility of the method through the measuring of the CAA and separated-component circuit. Moreover,the posibility is given to establish the expert system for the filter design.
