| Popis: | This paper deals with the design, analysis, computer simulation, and experimental measurement of fractional-order sinusoidal oscillator with two current conveyors, two resistors, and two fractional immittance elements. The used conveyor is based on the bulk-driven quasi-floating-gate technique in order to offer high threshold-to-supply voltage ratio and maximum input-to-supply voltage ratio. The supply voltage of the oscillator is 1 V, and the power consumption is $$74\,\upmu \hbox {W}$$74μW, and hence the proposed oscillator can be suitable for biomedical, portable, battery-powered, and other applications where the low-power consumption is critical. A number of equations along with graphs describing the theoretical properties of the oscillator are presented. The unique features of fractional-order oscillator are highlighted considering practical utilization, element computation, tuning, phase shift of output signals, sensitivities, etc. The simulations performed in the Cadence environment and the measurements of a real chip confirm the attractive features of the proposed oscillator. |
