Practical Design and Evaluation of Fractional-Order Oscillator Using Differential Voltage Current Conveyors
Original language description
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 (BD-QFG) 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 µW, 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.
