By utilizing two new operational transresistance amplifier (OTRA)-based generic configurations, we have discussed ten second-order inverse band reject filter circuits and 12 inverse all pass filter circuits. The usability of the inverse filter configurations has been established by SPICE simulations and also by hardware experimentation. In these experiments, integrated circuit from analogue devices, namely AD844-type current feedback operational amplifier, has been used to realize the behaviour of OTRA.

基于OTRA的反向全通和反向带阻滤波器的生成

通过利用两个新的基于运算跨阻放大器（OTRA）的通用配置，我们讨论了十个二阶逆带阻滤波器电路和12个逆全通滤波器电路。逆滤波器配置的可用性已通过SPICE仿真以及硬件实验得以确立。在这些实验中，模拟器件的集成电路，即AD844型电流反馈运算放大器，已被用于实现OTRA的性能。
