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.展开更多
