Abstract :
This paper presents new approaches for realizing high quality factor continuous-time asymmetric-slope second-order band-pass filters based on concepts of fractional-order filters. Two non-conventional transfer functions and two possible circuits, one based on a floating Frequency Dependent Negative Resistor (FDNR) and one based on a floating inductor both using a fractional capacitor, are proposed. Examples of active filter design are supported by PSPICE simulations and experimental results. Furthermore, a Field Programmable Analog Array (FPAA) realization is also presented.
