摘要: 本文提出以傳遞函數(shù)的信號(hào)流圖實(shí)現(xiàn)為基礎(chǔ),設(shè)計(jì)出一種新的通用高階可調(diào)OTA-C濾波器.該濾波器僅需要OTA器件和接地電容,適合于用MCS技術(shù)實(shí)現(xiàn).實(shí)驗(yàn)結(jié)果證明了它的可行性.

Abstract: A new universal tunable high-order OTA-C filter based on a signal-flow-graph realization of the transfer function is designed. The filter needs only OTAs and grounded capacitors, and it is convenient for realization with MOS technology. Experimental results are given to show its feasibility. -
