The design and realization of continuous-time fractional order circuits and their performance analysis have been presented. Here, a fractional order devices which is primarily used for realization of fractional order circuits, are described. Also a comparison between the fractional order circuits and its integer order counterpart has been presented. It can be shown by simulation that the fractional order circuits can be used for high frequency application without changing RC time constant of
