Two new configurations of third-order dual-mode (i.e. both voltage and current mode) quadrature sinusoidal oscillator using a newly reported active block, called the voltage differencing current conveyor (VDCC) have been presented in this manuscript. Both the proposed oscillators employ two VDCCs, three capacitors, and three resistors. The circuits are suitable for integrated circuit (IC) realization as all the passive components used in the circuits are grounded. In addition, the proposed configurations enjoy the following advantages: i) both the frequency of oscillation (FO) and the condition of oscillation (CO) are electronically tunable; ii) tuning of FO and CO are independent to each other; and iii) active and passive sensitivities are low. Non-ideal, parasitic and phase noise analysis of the circuits have been included to strengthen the design idea. PSPICE simulation results using TSMC 0.18 μm CMOS technology are given to verify the theoretical analysis. The operations of the proposed circuits are also verified experimentally wherein VDCC is realized using OPA860 ICs.

该手稿中介绍了两种新配置的三阶双模式（即电压模式和电流模式）正交正弦振荡器，它们使用了新近报道的有源模块，称为电压差电流传输器（VDCC）。两种建议的振荡器都使用两个VDCC，三个电容器和三个电阻器。该电路适用于集成电路（IC）实现，因为电路中使用的所有无源组件都已接地。此外，所提出的配置具有以下优点：i）振荡频率（FO）和振荡条件（CO）都是电子可调的；ii）FO和CO的调整彼此独立；iii）主动和被动灵敏度低。不理想，电路的寄生和相位噪声分析已经包括在内，以加强设计思想。给出了采用台积电0.18μmCMOS技术的PSPICE仿真结果，以验证理论分析。还通过实验验证了所提出电路的操作，其中使用OPA860 IC实现VDCC。
