摘要： The device described herein proposes an electronic active filter void of capacitors and inductors. The circuit utilizes only operational amplifiers (Op-Amps) and resistors, hence the name Op-R. Although capable of being constructed of lumped circuit elements this filter is intended for integrated circuit (IC) applications. Filtering of signals can be accommodated sub-audio through the video frequency range depending on the selected op-amp ICs. Low pass, band pass, high pass, as well as ban reject frequency responses are achievable. Although the circuits described herein are single input-single output, multiple inputs and outputs present no difficulty, being limited only by chip space. Temperature and production spread variations are also considered within the realm of tenability.
