  • Abstract
    A new family of second-order filters is introduced. When an external voltage amplifier is added to a second-order filter cell (passive or active), the characteristic frequency of the resulting filter can then be modified by acting only on the value of the gain of this amplifier. All the properties of these new filters are examined. Simulation results of a practical example are given to confirm the theoretical analysis.
