This document is the Accepted Manuscript version of the following article: Wenshan Zhao, Yigang He, and Yichuang Sun, ???Switched-current filter structure for synthesizing arbitrary characteristics based on follow-the-leader feedback configuration???, Analog Integrated Circuits and Signal Processing, (2015), Vol. 82 (2): 479-486. The version of record is available online at doi: 10.1007/s10470-014-0477-8 ?? Springer Science+Business Media New York 2015?? 2015, Springer Science+Business Media New York. A switched-current (SI) filter structure with follow-the-leader feedback configuration has been proposed for synthesizing arbitrary transfer functions. The double-sampling fully-balanced SI bilinear integrator and current mirror are employed as the building cells in order to enhance overall performance and make circuit design more flexible. Also, explicit design formulas are derived by using coefficient matching. The third-order low-pass and band-pass filter are designed as the examples. Simulation results confirm that the presented filter structure is very suitable for the operation with high sampling-to-cutoff frequency ratio, and can synthesize arbitrary filter characteristics precisely and easily while keeping low sensitivity
