Abstract :
A voltage-mode filter employing three current-feedback amplifiers, two grounded capacitors and three floating resistors is presented. The proposed circuit offers the following advantages: realisation of notch, lowpass and bandpass signals from the same configuration, no requirements for component matching conditions, orthogonal control of ω0 and Q, and the use of two grounded capacitors ideal for IC implementation, and low active and passive sensitivities and cascadability
