This paper introduces a mixed-mode biquadratic circuit employing DVCCs (differential voltage current conveyors) and grounded passive components. The biquadratic circuit can perform mixed-mode operation selecting the input and output terminals. And the circuit enables LP (low-pass), BP (band-pass), HP (high-pass), BS (band-stop) and AP (all-pass) transfer functions by suitably choosing the input terminals. The circuit parameters ω₀ and Q can be tuned orthogonally through adjusting the passive components. The biquadratic circuit enjoys very low sensitivities with respect to the circuit components. The achievement example is given together with simulation results by PSPICE.
