Generalized Fully Adjustable Structure for Emulating Fractional-Order Capacitors and Inductors of Orders less than Two

摘要: A novel scheme suitable for the emulation of fractional-order capacitors and inductors any order less than 2 is presented in this work. Classically, impedances are characterized frequency domain by a Laplacian form $$s^{\pm \alpha }$$ with an $$0<\alpha <1$$. The ideal inductor capacitor correspond, respectively, to setting $$\alpha =\pm 1$$. In range $$1<\alpha <2$$, can still be obtained before turning into Frequency- Dependent Negative Resistor (FDNR) at 2$$. Here, we propose electronically tunable impedance emulator adjustable full <2$$. values emulated capacitance/inductance, as well bandwidth operation, also adjustable. post- layout simulation results confirm correct operation proposed circuits.
