Design of Fractional-Order Emulator of the Cardiac Tissue Electrode Interface

An implementation of the cardiac tissue electrode interface fractional-order model is presented in this work. The realization of the required fractional-order capacitor emulator has been performed in such a way that the spread of the capacitor and transconductance values is minimized. Thanks to the employment of Operational Transconductance Amplifiers (OTAs) as active cells, the proposed scheme offers the benefits of electronic tuning and capability of implementation in monolithic form.
