The discretization of a fractional-order differentiator s^nu, where nu is a real number 0<nu<1, is an important issue in digital signal processing. This letter gives the analytical expression of the convergents of a continued fraction expansion of the binomial (1+s)^nu to get a rapidly convergent, stable, minimum-phase approximation of digital differentiators.
