摘要
基于教学实践,提出一种基于二端口级联的回转器设计方法,并采用运放加以实现。将回转器的传输参数矩阵分解两个子传输传输矩阵之积,然后讨论两个子传输传输矩阵的实现电路,再将这两个实现电路级连,得到回转器的实现电路。使用运算放大器实现电路中的负电阻与受控源,并以Multisim仿真验证该方法的正确性。所述回转器设计与实现方法对电路理论的教学具有一定的启发与助益。
From the teaching practice, this paper proposes a design method of gyrator based on cascade connection of two-port network, which is realized by operational amplifiers. The transfer parameter matrix of gyrator is decomposed into the product of two sub-transfer matrices. The realized circuit of the two sub-transfer matrices is discussed. The two implementation circuits are connected in cascade to obtain the realized circuit of the gyrator. The operational amplifiers are used to realize the negative resistor and controlled source in the circuit. The correctness of the method is verified by Multisim simulation. The design and implementation method of gyrator discussed is helpful for the teaching of circuit theory.
