摘要

A new three-input and single-output current-mode biquad filter using one plus-type inverting second-generation current conveyors (ICCIIs), two grounded capacitors and two resistors is presented. This filter can simultaneously realize five generic low-pass, band-pass, high-pass, band-reject and all-pass filtering signals. H-Spice simulations with 0.35 μm process are used to validate filter feasibility, operating frequency ranges, and especially, very low sensitivities for the new band-pass, band-reject, and all-pass biquads. Moreover, the new universal biquad filter is much more accurate in output responses and has much larger operating frequency range than a previous old one constructed by a single second-generation current controlled conveyor (CCCII), two grounded capacitors, and one floating resistor.
