Abstract
A simpler macromodel than that proposed by G. Boyle et al. (1974) is presented. This macromodel does, however, include a large number of operational amplifier characteristics. Advantages of this macromodel include: it is simpler, it is always feasible to calculate parameters, it can be more suitable for AC analysis, and it is quicker to simulate. For the given circuits, the DC analysis with this macromodel was about four times shorter than with the Weil-McNamee (1978) and about two and a half times shorter than with the macromodel of Boyle et al. The duration of transient analysis was up to seven times shorter with the new macromodel than with the Weil-McNamee model, and up to 50% shorter than with the Boyle et al. macromodel. >
