摘要
应用增广电路研究了由一个连续型运放以及任意数目的电阻和独立源构成的电路的若干特性,着重讨论并得出该类电路最多只可能存在三个直流平衡点的结论。
Properties of one OP-AMP circuits containing positive feedback structures are investigated in detail by employing the concept of augmented circuits.Among these properties is the fact that each OP-AMP port-voltage is a monotone function of the augmented citcuit.By utilizing these properties,it is established that one OP-AMP circuits can possess at most three DC solutions for all possoble circuit configurations.
