【Abstract】 The design method of the high-order elliptic highpass filter is presented using the E type frequency dependent negative resistor, grounded simulated inductor and floating grounded simulated inductor based on current conveyor. The active filtering circuit by this design enjoys low sensitivities character of the passive ladder network prototype. Design example of five-order elliptic high-pass filter and its PSPICE simulation result are also given.更多还原
