Description
Summary:A new current-mode low input impedance second order allpass and notch filter with single current follower was proposed in this work. Circuit contains one dual output current-follower, two capacitors and four resistors. Circuit shows a good sensitivity characteristics for all passive components. Filter performance is tested in SPICE simulation with a realised CMOS current follower.
