Application Design of Op-amp Circuit Based on Software Simulation Verification
Xing Yalang · Modern Electronics Technique · 2010
The working principles of integrator and filter are summarized.The computation method of typical circuit with operational amplifier is described.The input and output expressions are deduced and are verified by Proteus simulation software.It indicates that the result obtained by the software simulation is identical with that of the theoretical calculation.A detailed design method about a sample circuit of voltage feedback is explained.The variation of the input signal can be better reflected by the circuit.Aiming at the shortcoming of phase calculation when the method of the filter quick design is adopted,it is pointed out that the compensation quantity can be achieved accurately and quickly by software simulation.
