Popis: In this paper, low-voltage active elements based a general filter topology, which provides fractional order low-pass, high-pass, band-pass and band-reject filter responses at the same circuit, is introduced. The designed circuits are simulated by employing 0.35um TSMC CMOS technology parameters as well as SPICE software. The power supplies are +/- 0.75 V. The power dissipations of simulated filters are below ten microwatts. The introduced circuit topology offers electronically adjustment of the order, coefficients and frequency response of the related filter without any structural change on the proposed general circuit topology. Furthermore, only grounded capacitors are used in the circuits. At the same the designed topology is based on resistor-less realization. Finally, the introduced topology is also verified experimentally.
