Nisha Walde, Syed Naseem Ahmad . New Current-Mode Second Order Filter using Current Feedback Amplifiers (CFAs). International Journal of Computer Applications. 86, 16 ( January 2014), 10-12. DOI=10.5120/15068-3432
Abstract
A new configuration for realizing current- mode multifunction filter using current feedback amplifiers for a single current input source is presented. The proposed current-mode circuit realizes simultaneously low pass, high pass and band pass filters where as notch and all-pass filter functions can also be realized by addition and/or subtraction of various filter functions without any substantial hardware requirement. The proposed circuit has low active and passive sensitivities and employs generally grounded capacitors. These filters also enjoy grounded-resistance-control of the parameters ω0 and Q0.
