Based on the analysis of the theory , the paper put forward the method of the analysis and design of the sc filter by the discrete time signal method using the basic switch blocks combined with the fabrication convenience , mature technology , low power consumption , higher integrated cmos process 在理論分析的基礎(chǔ)上,論文提出了結(jié)合現(xiàn)在尋求代工方便、技術(shù)比較成熟、功耗低、集成度高的cmos工藝技術(shù),利用常用的基本開(kāi)關(guān)模塊,用離散時(shí)間信號(hào)的方法來(lái)分析和實(shí)現(xiàn)開(kāi)關(guān)電容濾波器。
