β¦ Synopsis
The proposed macromodel in this paper precisely simulates almost all performance characteristics of integrated circuit operational amplifiers. It is shown by an example that the model bears very strong resemblance to actual circuits, A detailed comparison with other existing models demonstrates the great advantages of the proposed model. The simplicity and accuracy together with the employment of the most popular circuit simulator SPICE2 enable design engineers to use the macromodel on CAE workstations for all general purpose applications.

The relationship between common mode rejection and positive and negative power supply rejections of operational amplifiers is derived and compared with symmetrical power supply rejection. The results are used to develop a macromodel which provides a correct representation of the terminal voltages at
