Original Abstract

Transformation of the classical KHN (Kerwin-Huelsman-Newcomb) 2nd-order filter into the current mode structure containing the CDTA (Current-Differencing Transconductance Amplifier) active elements is described. The resulting structure consists of three CDTAs 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.
