摘要

本文提出了一种分数阶振荡器的直接设计，该振荡器采用新颖的简单阻抗逆变器(实现差分电压电流输送跨导放大器作为有源元件)，用于构建并联LC谐振器，并且还需要负电阻。设计假设两个输出波形的恒定幅度比和相移155度(-25度)假设两个相同的恒相元件(分数级电容器)。通过仿真验证了该方案的主要优点，即输出电平比的稳定性和生成波形之间的相移。

Practical Design of Fractional-Order Oscillator Employing Simple Resonator and Negative Resistor

This contribution presents straightforward design of a fractional-order oscillator employing novel simple impedance inverter (implementing differential voltage current conveyor transconductance amplifier as active element) used for construction of parallel LC resonator and requiring also negative resistor. Design supposing two output waveforms with constant amplitude ratio and phase shift 155 degrees (-25 degrees) supposes two identical constant phase elements (fractional-order capacitors). The key advantages of our solution, stability of ratio of output levels and phase shift between generated waveforms, were confirmed by simulations.
