Realization Method of Controlled Sources Based on Operational Amplifier
This paper discusses the realization method of four controlled source models and its application.Simulation results by Multisim software verify the correctness of the realization circuits.Firstly,the operational amplifier based noninverting amplifier is applied to realize the voltage-controlled voltage source.On this basis,an explanation method of circuit design of negative resistor is given.With the realization circuits of voltage-controlled voltage source and negative resistor,the realization circuits of the other three controlled sources are given through the equivalent transformation of circuit.The discussion of this paper provides a design idea for the realization of general two port circuits.
