Passive fractional-order components based on resistive-capacitive circuits with distributed parameters

The paper deals with the analysis and mainly synthesis of passive fractional-order elements (FOEs). Pointing out the disadvantages of the most frequently used solutions, the utilization of resistive-capacitive circuits with distributed parameters for the design of FOEs is further discussed. This approach is based on creation of resistive, capacitive and conductive layers on a substrate. Examples of these devices along with simulation and measurement results are presented. A platform for analysis, synthesis and trimming of these components is also described, which allows to adjust required parameters of the elements after fabrication.
