Original Abstract

A novel second-order current-mode filter is proposed. It consists of three CDTAs (Current-Differencing Transconductance Amplifiers) and two grounded capacitors. The proposed filter has a low-impedance current input and three current outputs, realizing three basic transfer functions (lowpass, highpass, and bandpass), which can easily be combined to implement transfer functions with various transfer zeros. Influence of basic real properties is demonstrated by SPICE and symbolic analyses.
