Abstract :
Using a current feedback amplifier (CFA), new series resistor-inductor and capacitor-frequency-dependent negative resistance configurations are proposed. Second-order highpass, lowpass and bandpass filters using the proposed circuits are also presented. Experimental results that confirm the theoretical analysis are obtained
