Abstract :
Two configurations for the design of single-CCII-biquad filters with high input impedance are presented. They can synthesize lowpass, bandpass, highpass, allpass, and notch filtering functions with a single CCII connected to five passive one-port RC elements. The quality factor and natural frequency of the proposed SCBs are insensitive to the voltage tracking error of the CCII. Experimental results which confirm theoretical analysis are presented. The circuits studied are illustrative of the versatility of the CCIIs
