Abstract :
The concept and properties of an active filter with a fourlayer distributed RC line in a feedback loop are presented. Due to specific properties of the four-layer RC line, it is possible to obtain zeroQ-sensitivity of the filter to active-element gain variations. A design procedure for the bandpass filter with prescribed Q and center frequency\omega_{o}-values is given.
