Nonlinear Integrator With Zero Phase Shift

In the present paper a nonlinear integrator is introduced which produces zero phase shift in comparison with -90° phase shift of linear integrator and the phase of -38° of nonlinear integrator introduced by Clegg [1]. The proposed nonlinear integrator is a combination of a 90° phase lead nonlinear network and a linear integrator. Synthesis and operation of the non-linear integrator as well as possible applications are also presented.
