A new voltage-mode fractional-order oscillator, employing in total 12 Metal-Oxide-Semiconductor (MOS) transistors, is introduced in this paper. The proposed circuit is composed of two operational transconductance amplifiers, two inverting voltage buffers, one resistor, and two fractional-order capacitors. Compared with the corresponding already introduced fractional-order oscillators, it offers the...
In this study, a new voltage-mode fractional-order oscillator using two unity-gain voltage buffers, two operational transconductance amplifiers, one resistor, and two capacitors is presented. The design procedure of integer-order as well as fractional-order oscillator employing in total 20 MOS transistors is discussed. Effects of fractional-order capacitors on amplitude, phase, condition of oscillation,...
The transfer function of fractional-order differentiators and integrators can be approximated through the utilization of appropriate integer-order transfer functions. Efficient tools towards this goal include the Continued Fraction Expansion as well as the Oustaloup's approximations. In this paper, the accuracy of the expressions derived through the various orders of these approximations, in terms...
