Wider Passband Third-Order Active-R Filter with Multifeedback Signal for Different Center Frequencies (f0)

Adnan Abdullah Qasem; G. N. Shinde

Wider Passband Third-order Active-R Filter with Multifeedback Signal for different Center Frequencies f0 configuration is proposed. This paper discusses a new configuration to realize third-order low pass, band pass and high pass. The presented circuit uses Multifeedback signal, OP-AMP and passive components. This filter is useful for high frequency operation, monolithic IC implementation and is easy to design .This circuit gives three filter functions low-pass, high-pass and band-pass. This filter circuit can be used for different cut-off frequencies f0 with high passband gain. This gives better stopband attenuation and sharper cut-off at the edge of the pass-band. Thus the response shows wider passband. The Ideal value of this filter circuit which are closed to Ideal value of third-order active-R filter is at f0
