Abstract
A voltage-mode filter employing three current-feedback amplifiers, two grounded capacitors and three floating resistors is presented. The pr oposed circuit offers the following advantages: realisation of notch, lowpass and bandpass signals from the same configuration, no requireme nts for component matching conditions, orthogonal control of omega(0) and Q, and the use of two grounded capacitors ideal for IC implementat ion, and low active and passive sensitivities and cascadability.
