SCN雙二次狀態(tài)變量法和優(yōu)化設(shè)計
THE DESIGN OF SCN IN THE BIQUADRATIC STATE-SPACE AND ITS OPTIMIZATION
-
摘要: 本文介紹了SCN雙二次狀態(tài)變量設(shè)計法。這種方法把n個狀態(tài)的n階濾波器壓縮成用n/2個狀態(tài)來描述,從而減少了設(shè)計過程中的內(nèi)存需要量。文章對電路穩(wěn)定性做了詳細(xì)的討論,提出了與EL-Masry(1981)相異的穩(wěn)定條件。文中考慮了電路設(shè)計中存在的參數(shù)自由度,并用它進(jìn)行了網(wǎng)絡(luò)的優(yōu)化設(shè)計。最后用設(shè)計實例驗證了作者的設(shè)計和理論。

Abstract: An optimal design of the switched-capactitor network (SCN) in the biquadratic state-space is developed in this paper. Only n/2 states are needed to describe n-state filters in the design, so that many storages can be saved. After discussing the stability of the circuits in detail, the stable conditions which differ from EL-Masry (1981) are given. The optimum design of networks is made by the parameter freedom which exists during the design of the circuits. And an example is given for proving the corectness of this design method. -
