ABSTRACT
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 ω0 and Q can be set orthogonally adjusting the
circuit components. An achievement example is given together with simulation
results by PSPICE.
KEYWORDS
Analog circuits, biquad responses, plus type DVCCs.
