The exact design methods of switched-current filters are summarized, such as the director synthesis of z-plane, euler mapping, state variable analysis, matrix decomposition, and signal-flow-graph simulation of the lc and switched capacitor prototypes . at the same time, a modified left decomposition matrix method is proposed to overcome the usual problems of large silicon area, high sensitivity and component spreads by minimizing the input circuits . examples of switched-current low-pass, high-pass and band-pass filters are given to verify the feasibility of these methods 總結(jié)分析了實現(xiàn)高精度開關電流濾波器設計的各種實用方法,包括z域綜合法、歐拉映射法、模擬無源lc網(wǎng)絡和開關電容網(wǎng)絡的狀態(tài)變量法、矩陣分解法和信號流圖轉(zhuǎn)置法,并對左分解法加以整理改進,提出一種更為簡潔的設計結(jié)構(gòu),通過減化輸入電路克服一般電路中存在的占用硅片面積大、靈敏度高等問題。
It is desirable for all related insiders and outsiders to discern all potential risk in advance . this paper, with the adoption of special treatment resulted from abnormal financial position as the indicator of financial distress, the univariate variable analysis and multiple variable analysis as the research approach and some financial ratios as variable, tries to find an optimal financial distress prediction model of chinese manufacturing listed companies based on public accounting data . our finding demonstrate that five general financial ratios and three ratios concerning the cash flow have better predicting ability, the erroneous classification ratio are low . these five general financial ratios are earning per share, return on net assets, return on gross assets, growth rate of net profits, growth rate of net assets; the three ratios concerning the cash flow are net cash flows from operating activities per share, net re-earnable cash flows / current liability, net cash flows from operating activities / net profit 研究結(jié)果表明,在單變量分析中,每股收益、凈資產(chǎn)收益率、總資產(chǎn)報酬率、凈利潤增長率、凈資產(chǎn)增長率這5個財務比率的錯分率較低、預測能力較強;經(jīng)營活動凈現(xiàn)金流量與凈利潤之比、每股經(jīng)營現(xiàn)金流量、可重復賺取的現(xiàn)金凈流量與流動負債之比這三個現(xiàn)金流量財務比率對于預測上市公司財務困境具有有效性;多變量分析中,應用費雪判別分析和典則判別分析得到兩個判別模型,在典則判別分析中,應用兩種方法確定所建模型的最佳分界點,檢測證明應用所得兩個判別模型進行財務困境預測的準確率很高。
