【摘要】 本文在最少有源元件的前提下探讨了有源梯型模拟的电路结构。并就 NIC、FDNIC、GIC 三种形式作了一定的阐述,给出了 FDNIC 的两种新电路,考虑了电路形式中非理想因素的影响。用这些电路所实现的有源滤波器都具有较好的效果。更多还原

【Abstract】 We have studied the circuti structure of active ladder simulation under the condi- tion of the minimum active elements.Three circuit forms,NIC,FDNIC,GIC,are described,two new PDNIC circuits are given,and the influences owing to the non-ideal effects of different circuit forms are considered.It is shown that the realized active filters by use of these circuits have respectively good results.更多还原
