摘要

多相正弦振荡器(MSO)可用于各种电气和电子应用。本研究旨在设计一种采用电压差分差分输入缓冲放大器(VD DIBA)的MSO。设计过程基于级联一阶低通滤波器。每相由一个VD-DIBA、两个电阻器和一个接地电容器组成。一种不需要额外放大器的奇相系统。在不影响条件的情况下,通过偏置电流对频率进行电子控制。正弦波振幅和每个波形之间的相位差是相同的。所提出的MSO被设计为获得三相波形(n=3)。PSPICE仿真验证了所提出的振荡器在±0.9V电源下具有0.18μm TSMC CMOS参数的性能。所提出的MSO的可行性也通过使用由商用集成电路(IC)构建的VD-DIBA的实验进行了验证,该集成电路具有±5V电源。模拟和实验结果与理论预测一致。

Electronically Tunable Voltage-Mode Multiphase Sinusoidal Oscillator with Low Output Impedance Nodes Employing VD-DIBAs
The multiphase sinusoidal oscillator (MSO) is useful for various electrical and electronic applications. This study aims to design an MSO employing voltage differencing differential input buffered amplifiers (VD-DIBAs). The design procedure is based on cascading the first-order low-pass filter. Each phase consists of a VD-DIBA, two resistors, and a grounded capacitor. An odd-phase system without requiring an additional amplifier. The frequency is electronically controlled through the bias current without affecting the condition. The sinewave amplitudes and the phase difference between each waveform are identical. The proposed MSO is designed to obtain three-phase waveforms (n = 3). PSPICE simulation demonstrates the performance of the proposed oscillator with 0.18 μm TSMC CMOS parameters with ±0.9 V power supply. The feasibility of the proposed MSO is also verified with experiments using the VD-DIBA constructed from commercial integrated circuits (ICs) with a ±5 V power supply. The simulated and experimental results align with theoretical predictions.
