Combined Applied Technology of Minimum Phase Shifting for Integrated Operational Amplifier

This paper points out the limitations of traditional methods since the analysis of how to reduce the phase shifting of integrated Op Amps. Then, the paper introduces a thought of the reasonable combination of matching dual and triple Op Amps with a single IC, forms a method of minimum phase shifting of an active feedback frequency, and discusses the combined applied technology of minimum phase shifting for the integrated OP Amps, which involves electric circuit design, mathematical deduction, comparison and calculation of actual parameters. The technology extends the bandwidth greatly and effectively given phase error. It is very important to electric circuits and systems which have a critical requirement for phase shifting error.
