A new CFOA-based low frequency lowpass filter for biomedical applications

A new floating active inductance (FAI) realization is presented. The FAI is used to construct a low frequency low-pass filter with cutoff frequencies in the low frequency region. Practical results obtained using the current-feedback operational-amplifier (CFOA) AD844 confirm the functionality of the proposed circuit. The proposed low frequency low-pass filter would be useful for biomedical applications with frequencies around 100 Hz.
