Abstract

A new universal voltage-mode second-order filter circuit is presented. The circuit uses three current-feedback operational amplifiers, three grounded capacitors and three resistors. The circuit has three inputs and three low-impedance outputs and can realize all the standard filter functions, lowpass, highpass, bandpass, notch and aIlpass, without changing the circuit topology. The proposed circuit enjoys independent grounded-resistance control of the parameters wo and wo/Qo, as well as low active and passive sensitivities.
