OTA正弦振荡器的系统产生方法

Systematic Generation of Sinusoidal Oscillators Using OTA's

本文以双二次传递函数电压放大器为基本模块，采用信号流图（ＳＦＧ）方法。设计了四大类ＯＴＡ－Ｃ正弦振荡器。第一类除包括当今流行的四种电路外，其余的电路和另三类是迄今尚未见诸发表的新电路。

Based on the building blocks of biquadratic transfer function and voltage amplifer, and by using the SFG approach, four families of OTA-C sinusoidal oscillators are designed. The first family includes not only the currently popular four types of circuits,but also some new circuits,which, as well as the other three families of circuits, have not been seen in published literafures so far.
