Single-input multiple-output signals third-order active-r filter for different circuit merit factor (Q)‎

Abstract EN

Single-input Multiple-output Signals Third-order Active-R Filter for different Circuit Merit Factor Q Configuration is proposed.

This paper discusses a new configuration to realize third-order low pass, band pass and high pass.

The presented circuit uses Single-input Multiple-output signals, OP-AMP and passive components.

This filter is useful for high frequency operation, monolithic IC implementation and it 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 merit factor (Q) with high pass band gain.

This gives better stop-band attenuation and sharper cut-off at the edge of the pass-band.

Thus the response shows wider pass-band.

The Ideal value of this filter circuit which is closed to Ideal value of third-order active-R filter is at 0.8≤ Q ≥6.

The advantages of this circuit are reduction in size and weight, increased circuit reliability, more economical and easy for manufacturing.
