A Low-Power Compact DDCC Based Fractional-Order Filter

摘要

This paper presents a new design to realize fractional-order lowpass filter. In this design, a single differential difference current conveyor (DDCC) is used as an active building block (ABB), which makes the design power efficient and compact. This filter consists of two fractance devices with orders α and β which provide the additional control on the system response. Dependency of system response on α and β is analyzed by MATLAB simulations. Further, the effects of current voltage tracking errors are investigated using Monte Carlo analysis. Finally, the circuit is simulated in PSpice environment using R-C ladder network based fractional-order capacitor, and the obtained results are compared with the theoretical results.
