A Novel Plus Type DVCC-Based Current-Mode Biquad

This paper presents a novel current-mode biquad using only plus type DVCCs (differential voltage current conveyors).The circuit enables LP (low-pass), BP (band-pass), HP (high-pass), BS (band-stop) and AP (all-pass) responses by the selection and/or addition of the circuit currents with no component matching constraints.Moreover the circuit parameters ω 0 and Q can be set orthogonally adjusting the circuit components.An achievement example is given together with simulation results by PSPICE.
