    該方案研究獲得的實驗結果表明：這種具有創新特色的交流變頻調速實驗系統可實現電動機組之間直接電磁轉矩方式的負載關系，可方便地獲得電動機在反應或位能負載特性下四象限運行的連續控制過程，並實現了任意負載方式下再生能量的全部回饋利用，任意負載下系統消耗功率僅占電動機實際負載功率的30 %以下。
  2. However, it is difficult to make the product available because most of the academic institution focused on certain aspect only. the experts indicate that the ic designers should know more about the system though they don ’ t design the system directly. it points out a way for us ic designers when we are engaged in the research work

    本文提出的開關變換器，利用反饋原理將輸出電壓穩定在某一需要的值，根據負載的不同而採取兩種控制模式，即脈沖寬度調制（ pwm - pulsewidthmodulation ）模式和脈沖頻率調制（ pfm - pulsefrequencymodulation ）模式。
  3. In the fourth chapter, a fourth - order chebyshev low - pass filter employs new low voltage, highly linear, wide inputting range transconductor is proposed, then we presents a new circuit to tune gm value of transconductor accurately, which employs a new switched - capacitor circuit to change the bias current of transconductor, a third order elliptical function low - pass filter with accurate tunable frequency has been designed using transconductor that is not only with voltage common - mode negative feedback, but also with varying bias - triode transistors which can improve the linearity of this circuit

    第四章：提出了一種新的低電壓、高線性度、寬輸入范圍跨導，並由此設計實現了四階切比雪夫（ chebyshev ）低通濾波器，接著提出了一種寬輸入范圍且具有電壓共模負反饋的全差分跨導，並採用一種新的開關電容電路實現跨導值gm精確可調，從而可以設計得到高性能具有精確截止頻率的跨導-電容三階橢圓函數濾波器。
  4.
