| 摘 要： | 本文介绍一组（12个）新的正弦振荡器，这组振荡器使用两个运算放大器，其振荡频率不受单极点有源元件增益带宽之积的影响。这种特性是由本文所介绍的电路结构取得的，即不需要调节。

| Abstract: | In this paper, a new set of 12 sinusoidal oscillators is introduced. These oscillatorsuse two opamps and their oscillation frequency is independent of the gain-bandwidth prod-ucts of these active elements when a single pole rolloff model is considered. This property isachieved by virtue of the configurations introduced in this paper, i. e., no adjustment is re-quired. |
