Generation of OTRA-Based Inverse All Pass and Inverse Band Reject Filters

摘要

abstract_textpBy 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./p/abstract_text
