Originální abstrakt

This paper brings novel first-order bilinear two-port section (also called as two-port block). New topology reduces complexity and minimizes impact of fabrication dispersion (tolerances) of passive elements on transfer features in comparison to previously reported solutions. Developed bilinear section was applied for arbitrarily equalized transfer response operating from tenths of Hz to hundreds of kHz. Important application of bilinear section in synthesis of fractional-order differentiator and integrator was verified for mathematical order a = 0.25 operating from tens of Hz to tens of kHz, i.e. more than two decades with phase error in range of +/- 3 degree. Features of proposed devices were verified by PSpice simulations.
