Design and Simulation of CFOA Based Higher Order Low Pass Filter

High order Filters are used for many applications. These types of filters provide higher attenuation at frequencies beyond the break frequencies. Current feedback operational amplifiers prove to be practically well suited for designing the filters for high frequency applications. In this paper the author proposed the design of second-order low-pass Butterworth filter for higher frequency application based on CFOA (Current feedback operational amplifier) using AD844 IC. The experimental results done using NI-Multisim software, ultiboard results and 3D view of the circuit are also shown in this paper
