Abstract

Two new configurations for the design of single second-generation current conveyor (CCII) biquad (SCB) filters with high-input impedance are presented. They can synthesize low-pass, bandpass, high-pass, all-pass, and notch filtering functions with a single CCII connected to five passive one-port RC elements. The active and passive sensitivities are calculated in order to determine the suitable domain for filtering applications. The quality factor and natural frequency of the proposed SCBs are insensitive to the voltage tracking error of the CCII. Experimental results that confirm the theoretical analysis were obtained. The circuits studied show the versatility of the CCIIs
