Original Abstract

This paper deals with the modified current-feedback operational amplifier (MCFOA) that is used in two voltage-mode (VM) frequency filters. Both structures presented employ single active and five passive elements. Circuits enable realizing a low- (LP), band- (BP), and high-pass (HP) filter responses without changing the circuit topology. There is no requirement for additional component or rotation of component to realize band-stop (BS) and all-pass (AP) filter function. Moreover, the independent adjustment of the quality factor Q by varying the value of single passive element without affecting of the natural frequency w0 is allowed. All the passive and active sensitivities are low. In the PSPICE simulations the BJT simulation model of the MCFOA and its possible realization using the UCC-N1B 0520 integrated circuit are used to confirm the workability of the proposed circuits.
