| Abstract: | This paper points out the limitation of traditional method after the analysis of how to reduce the phase error of integrated Op Amps. Then,the paper introduces an idea of the reasonable combination of matching second and third Op Amps with a single IC,forms a method of minimum phase shift of active feedback compensation,and discusses the combination applying technology of minimum phase error for the integrated OP Amps,which involving electric circuit design,mathematical deduction and comparison and calculat... |
