Voltage-Mode High Input Impedance Inverting and/or Non-Inverting Highpass, Bandpass and Lowpass Filters Using Three CCIIs
J. Horng, H. Tang and Y. Wen
Two new configurations for realizing voltage-mode high input impedance inverting and/or non-inverting highpass, bandpass and lowpass filters, simultaneously, using three second-generation current conveyors (CCIIs), four grounded capacitors and three grounded resistors are presented. The proposed circuits offer the following features: the versatility to synthesize various inverting and/or non-inverting highpass, bandpass and lowpass signals, simultaneously, from the same configuration; no requirements for component matching conditions; the use of only grounded capacitors and resistors; high input impedance; orthogonal controllable of resonance angular frequency and quality factor; low active and passive sensitivities and simpler configuration due to the use of only three CCIIs.
