ABSTRACT
This paper introduces
current-mode IAFs (inverse active
filters) employing DVCCs (differential voltage current conveyors) and grounded
passive elements without the parasitic effects. The IAFs enable ILP (inverse low-pass), IBP (inverse band-pass) and
IHP (inverse high-pass)
responses by adding the circuit current outputs suitably. Additionally the
circuit parameters ω0 and Q can be set orthogonally adjusting the
circuit passive elements. An achievement example is given together with
simulation results by PSPICE.
KEYWORDS
