Abstract :
A comparison of two simple models for operational amplifiers is undertaken in this paper. One model is termed the one-pole rolloff model, and this model has been used with good results for several decades. The other model has been utilized from time-to-time in recent years. Three criteria are stated for a "good" model, and it is shown that one of the models fails to meet one of the criteria
