Method to Save Silicon Area by Increasing the Filter Order

Peter Nilsson, Mats Torkelson

Research output: Contribution to journalLetterpeer-review


The authors' intention is to show that there are other criteria when optimising digital filters than minimising the filter order. The final result in the form of minimum silicon area or few machine cycles in a high-speed custom DSP are aims that are important in a custom design process. It is not an axiom that the minimum order of the filter gives the optimum result. Algorithms with trivial coefficients will gain both in area and speed. As an example, they show a wideband digital filter for mobile communication
