摘要

本文提出了采用三个运算跨导放大器(OTAs)和两个分数阶电容的两种广义振荡器结构。利用一般分数阶振子定理，分析和推导了涉及分数阶元参数的振荡条件(CO)、振荡频率(FO)和相位的广义表达式。LM13700型OTA的库文件已用于Pspice仿真，以验证本通信中详细介绍的振荡器配置的工作。

Generalised Fractional-Order Oscillators using OTA

This paper presents two generalized oscillator configurations employing three operational transconductance amplifiers (OTAs) and two fractional-order capacitors. General fractional-order oscillator theorems are used for analysis and derivation of generalized expressions for condition of oscillation (CO), frequency of oscillation (FO) and phase involving parameters of fractional-order element (FOE). LM13700 type OTA’s library file has been used in Pspice simulation for verification of the working of oscillator configurations detailed in this communication.
