Current‐mode highpass, bandpass and lowpass filters using followers

Current‐mode highpass, bandpass and lowpass filters using followers Purpose – The purpose of this paper is to present two new follower‐based current‐mode multifunction filters. Each of the proposed circuits can realize highpass, bandpass and lowpass filters, simultaneously. Design/methodology/approach – The input terminals of the proposed current‐mode biquadratic filters are virtual grounded. The output terminals of the proposed circuits can be easily cascaded with the similar sections. Findings – Highpass, bandpass and lowpass filters can be obtained simultaneously from the proposed circuits using only one or two followers. Originality/value – The paper presents new ideas for follower applications. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Microelectronics International Emerald Publishing

Abstract

Purpose – The purpose of this paper is to present two new follower‐based current‐mode multifunction filters. Each of the proposed circuits can realize highpass, bandpass and lowpass filters, simultaneously. Design/methodology/approach – The input terminals of the proposed current‐mode biquadratic filters are virtual grounded. The output terminals of the proposed circuits can be easily cascaded with the similar sections. Findings – Highpass, bandpass and lowpass filters can be obtained simultaneously from the proposed circuits using only one or two followers. Originality/value – The paper presents new ideas for follower applications.
