Area Efficient Current Mode all Passes Filter and Notch Filter using Single CDBA

Abstract

In the proposed work, A single current differencing buffer amplifier (CDBA) in the current mode with application of second order notch filter and all pass filter is presented. The proposed circuit is suitable to realize the proposed operation by using of single CDBA with the current processing application of filter design also we have driven the performance of CDBA and area efficiency. A second order all-pass filter and notch filter are designed to define application in current mode processing with the single CDBA. The SPICE simulation results for frequency responses are incorporated to verify the theory.the work is done on 180nm technology.
