Graphical abstract
Implementation of the fractional-order Chen’s chaotic oscillator using a field-programmable analog array (FPAA). Charef’s method is applied to approximate the fractional-orders as ratios of two polynomials in the Laplace domain, which are implemented by first-order all-pass and low-pass filters in the FPAA.
