摘要
已知给定的单个或多个运放RC正弦振荡器具有四种明显不同的等效和稳定形式。(R。[j]。Boutin, december 1984]。本文提出了一种不同的结构，以克服均匀分布RC线(UR c)网络和基于可调频率正弦振荡器的单极放大器的频率限制。仿真和实验结果与理论吻合较好，谐波失真很小。该电路可适用于大规模集成电路工艺制造。
Novel technique using single pole amplifier in sinewave oscillator
It has been known that a given single or more op-amps RC sinusoidal oscillator has four distinctly different, equivalent, and stable forms. [R. Senani, Sept. 1987] [N. Boutin, Dec. 1984]. This paper's different structure have been proposed to overcome the frequency limitations associated with uniformly distributed RC line (UR Cs) network and single pole amplifier based adjustable frequency sinusoidal oscillator. The simulation and experimental results are in reasonably good agreement with the theories and have very low harmonic distortion. This circuit can be suitable for LSI process fabrication.
