中文摘要：

提出了一种全新的电流模式多相位正弦振荡器电路。该电路仅使用一个电流差分级联跨导放大器（CDCTA）和接地无源元件,能产生n（n为奇或偶）个等相位差的电流信号,电路结构简单、工作电压低、输出阻抗高、振荡频率高,而且振荡条件和振荡频率独立可调。计算机CADENCE软件仿真和流片测试结果验证了理论分析的正确性。

英文摘要：

A novel current-mode multiphase sinusoidal oscillator circuit was proposed. The realized circuit using single current differencing cascaded transconductance amplifier （CDCTA） and only grounded passive elements could yield n （n being odd or even） current-output signals equally spaced in phase. It enjoyed the characteristics of simple circuit structure, low-voltage, high-output impedance, high-frequency and independently electronic adjustable of oscillation condition and os- cillation frequency. CADENCE simulation and experimental results have been included to verify the theoretical analysis.
