VOLTAGE-MODE SITO MULTIFUNCTION FILTER USING ONLY TWO FTFNS

Özet

In this paper we present a new voltage-mode (VM) multifunction filter configuration using only twofour terminal floating nullors (FTFNs) and five passive elements. The circuit with a single input andthree outputs can simultaneously realise lowpass (LP), bandpass (BP) and highpass (HP) filterresponses. The natural frequency (ω0 ) and the bandwidth (ω /Q 0 ) can be orthogonally controlled.The passband gains of two filtering responses can be tuned independently. The active and passivesensitivities are low. Simulated results are included to verify the theoretical analysis.
