【 摘 要 】

References(14)Cited-By(2)A novel versatile single FDCCII-based voltage-mode universal biquadratic filter with three inputs and four outputs is presented. The proposed circuit can act as a multifunction voltage-mode filter with two inputs and four outputs and can perform simultaneous realization of voltage-mode bandreject, highpass, bandpass and lowpass filter signals from the four output terminals, respectively. On the other hand, it also can act as a universal voltage-mode filter with three inputs and a single output and can realize five generic voltage-mode filter signals without requiring any inverting input voltage signals and component-matching conditions. The proposed circuit employing single FDCCII, two grounded capacitors and two resistors, which are the minimum components necessary for realizing a second-order voltage-mode universal filtering response from the same topology. Both its active and passive sensitivities are low.
