Abstract: In this paper, two new voltage-mode universal biquadratic filters each with one input terminal and five output terminals are presented. Each of the proposed circuits can realize voltage-mode highpass, bandpass, lowpass, notch and allpass filter transfer functions, simultaneously, by using two plus-type differential difference current conveyors (DDCCs), two grounded capacitors and three resistors. Moreover, the proposed circuits have the following attractive advantages: (i) realization of all the standard filter functions from the same circuit configuration, (ii) employment of grounded capacitors that is ideal for integration and (iii) low active and passive sensitivities.
