A new multifunction configuration using a single current feedback amplifier (CFA) and a few RC components is presented. The analysis for the various signal processing function realizability had been carried out by utilizing the internal parasitic and transimpedance elements of the CFA (AD-844 or 846) device. The circuit implements the functions of integrator/differentiator, high-selectivity (Q ges 20) filters, and sinusoid oscillator (Q rarr infin) on the same topology with the appropriate design. Adjustment of the time constant (T), filter quality (Q), and oscillation frequency (omegao) may be obtained with single-component variation at extended frequency ranges (1-30 MHz). All of the proposed functional performances had satisfactorily been verified with PSPICE macromodel simulation and by hardware circuit implementation.
