Abstract :
The conventional lowpass-bandpass transformation (transformation of each element separately) is not applicable to active RC networks because it leads to networks also containing inductors. A modified transformation, including explicit design formulas, will be described, which is applicable to the design of active RC bandpass filters realised by cascading 2nd-order sections.
