摘要

本文提出了一种采用差分缓冲放大器(cdba)作为有源元件的多相正弦振荡器。该振荡器电路由n个级联有损积分器和n个逆变器组成，可产生2n个不同相位的正弦电压(180°/n和180”/n+180°)。振荡频率可以宽范围调节，约30年，通过有源元件的值。用AD844集成电路得到的实验结果证实了理论分析。

Realization of multiphase sinusoidal oscillator using CDBAs

A multiphase sinusoidal oscillator with the employment of current differencing buffered amplifiers (CDBAs) as an active element is presented in this paper. The proposed oscillator circuit is composed of n cascaded lossy integrators and n inverters, which can generate 2n different phase sinusoidal voltage (180°/n and 180"/n+180°). The oscillation frequency can be wide range adjusted, approximately 3 decades, through the value of active elements. Experimental results obtained using the AD844 ICs are given to confirm the theoretical analysis.
