In the design , a gradient - error and endge - effect tolerant switching scheme for 10 bit dac is presented . we explain how to select the dimension of the unit current source transistor and why this scheme has those properties and how to construct it 設計中采用了一種對剃度誤差和邊緣效應不靈敏的電流源晶體管布局方案,并從單位電流源晶體管尺寸的選取到整體方案都作了詳細的研究。
Through the analysis on the ratio of investment to output , we found that highway transportation obtained great strength from the development of market economy , which demonstrates the transition from strong to feeble , while the railway transportation did on the opposite direction 通過投入產出比的分析,發現了公路運輸從市場經濟發展中獲得了較大的力量,隨著市場經濟的發展而由弱變強的過程。而鐵路運輸隨著市場經濟的進一步發展由強向弱轉變,暴露出其對市場經濟信號反映不靈敏的弱點。
