Design of Simpson integrator at microwave frequency

In analog system designing integrators are preferred over differentiators due to stability and saturation problems. Integrators find applications in various field controls, wave shaping, image blurring, and microwave integrators. Simpson and Trapezoidal rule have advantages in sense of phase contribution providing by integrators, that is similar to ideal integrator phase response. Whereas Rectangular, two-point extrapolation and three-point rules of integrators suffer a fix amount of phase error. There is different digital integration rules can be fit for different microwave integrators structures i.e. decided by trial and error. In this paper proposed Simpson integrator at low frequency approximated to microwave frequency range.
