Current-mode KHN filter employing current differencing transconductance amplifiers
This study proposes a current mode (CM) KerwinHuelsmanNewcomb (KHN) filter employing only two current differencing transconductance amplifiers (CDTA) and two grounded capacitors. It is concluded that the circuit described here offers a simpler and more economical alternative to other CM KHN filters reported previously in literature.
