Title: Current-mode biquad employing single CDTA

Current-mode filters

Publisher: CSIR
Abstract: This paper presents a novel current-mode (CM) second-order filter, employing one current-differencing transconductance amplifier (CDTA), two grounded capacitors and one virtually grounded resistor. The filter provides two current outputs of lowpass (LP) and bandpass (BP) types for driving independent loads and one high pass (HP) current output, flowing through one of working capacitors. The results of the PSpice simulation, which utilizes the CDTA model on the level of CMOS transistor structure, are enclosed.
