摘要

本文提出了一种采用两个有源元件和四个接地无源元件产生多相正弦波的新电路方案。所提出的振荡器提供4个45°相移电压输出。合并额外的逆变器产生八相输出进一步显示。同时的电流输出也可以产生额外的输出级。研究了紧凑电路结构对非理想效应和寄生效应的影响，并给出了仿真结果，与理论结果吻合较好。作为一个有趣的应用实例，本文探讨了该方法在π/4-QPSK生成中的应用。

Sinusoidal Generator with π/4-Shifted Four/Eight Voltage Outputs Employing Four Grounded Components and Two/Six Active Elements

This paper presents a new circuit proposal for multiphase sine-wave generation, employing two active elements and four grounded passive elements. The proposed oscillator provides four 45° phase-shifted voltage outputs. Incorporation of additional inverters for generation of eight-phase outputs is further shown. Simultaneous current outputs can also be generated with additional output stages. The compact circuit structure is studied for nonideal and parasitic effects and simulation results are given, which are in good agreement with the theory. The utility of the proposal for π/4-QPSK generation is explored as an interesting application example with supporting results.
