Abstract :
A Switched Capacitors (SC) implementation of fractional integrator is proposed in this paper. Time and frequency domain result tests validate the feasibility and reliability of the SC circuit implementation. A detailed analysis of the influence of the non-idealities is proposed in order to obtain a design fit for Integrated Circuit (IC) implementation. The proposed approach may guarantee a good degree of approximation of the fractional differ-integral operator and therefore the possibility to realize a PIλDμ controller IC based on switched capacitors technology.
